Data Science for Beginners | Google Advanced Data Analytics Certificate
- If you've ever used an app to find the best way through traffic or received product recommendations while shopping online, you're already familiar with data analytics from the consumer end. According to some estimates, each person creates at least 1.7 megabytes of data per second on average. That roughly translates into over 2.5 quintilian megabytes of data being produced every single day worldwide.
As such, there's a huge demand now and for the foreseeable future for people who can organize data and interpret the stories locked within. As you approach this career pathway, you're likely to bring practical experience in problem solving, decision making, allocating resources, time management, and many of the skills that are particularly suited for the job of a data professional. Many companies are searching for candidates to fill positions in this fast-growing high-paying field. My name is Cassie and I've been a data scientist since before we called it data science.
I lead decision intelligence here at Google and I'll be your instructor for the first course of this certificate program. Before I became Google Cloud's Chief Decision Scientist, I worked as a data scientist in Google Research where I was involved with over 400 projects all across Google. One of my favorite things about the data science career is the tremendous variety, especially if like me, you're a naturally curious person. There are so many different flavors of project and challenge. Some of us choose to work on one project for years. Others get involved with several new projects every week.
The possibilities are endless. A data professional is a term used to describe any individual who works with data and/or has data skills. At a minimum, a data professional is capable of exploring, cleaning, selecting, analyzing, and visualizing data.
They may also be comfortable with writing code and have some familiarity with the techniques used by statisticians and machine learning engineers, including building models, developing algorithmic thinking, and or building machine learning models. Machine learning is an alternative approach to automation, expressing the way you want a task done by using data instead of explicit instructions. Machine learning is an important component of the modern data professionals toolkit.
To train a machine learning model, specialists put a bunch of potential data inputs through algorithms, tweak the settings, and keep iterating until promising outputs are produced. But training a model is only one small step in the professional machine learning journey. Machine learning techniques can also be used for data analytics and exploration with far fewer steps, and that's what you'll learn in this program.
You'll discover additional opportunities to explore machine learning through the course resources, so do check those out. Data professional work spans a wide range of industries and impact affects a multitude of products and services. As we'll discuss later, there are also lots of different roles and titles that focus on data professional work.

This is such a great time to grow and advance your career as a data professional. Your path to a career full of new opportunities awaits. Earlier I referenced the tremendous amount of data generated each day. It has become a byproduct of modern life.
For companies and organizations all this data can provide insight into the ways they operate and ultimately interact with their users and consumers. To obtain these insights, organizations need people with the ability to access, interpret and share the stories within their data. Organizations understand that data can inform decision-making and explain consumer trends and user behavior.
Data professionals use data insights to optimize products or services. There's a common phrase in data-driven decision making that references the untapped potential of data. The phrase is, "Imagine if we knew what we know?" Basically, it's a way of asking the following question, how can we take all that data that may already exist and translate it into meaningful and actionable insights? To gain insights, businesses rely on data professionals to acquire, organize, and interpret data, which helps inform internal projects and processes. Businesses seek those who can access data and understand its metrics. As a reminder, metrics or methods and criteria used to evaluate data both unnecessary before creating predictive models that can identify trends and inform best practices, and that's where you'll come in.
The combination of all these skills from statistics and scientific methods to data analysis and artificial intelligence all fall within the category of data science. Data science is the discipline of making data useful. To me, the idea of usefulness is tightly coupled with influencing real world actions. Some individuals with these skills may work on developing business insights and supporting strategic decision makers. Others may use data skills to fuel automation, testing, and analytic tool development. Still, others may focus on the analytic process itself by adapting modeling approaches to incorporate new and emerging technologies.
Data is the foundation for making future decisions. It's through our actions and decisions that we affect the world around us. Businesses and organizations need people like you who can think critically and analytically about how to directly address challenges and opportunities through data focused projects. The work of data professionals can provide businesses and organizations with details about their practices that can promote new approaches and innovation. This might make a little more sense if we take a closer look at an example, a global delivery company, for instance. Generally speaking, delivery companies are responsible for transporting goods to consumers.
A company as complex as this is going to have a number of different data inputs or streams that influence impact and affect the ways the business operates. These data inputs and streams may include, but are not limited to: weather and traffic patterns which affect when deliveries are projected to arrive, gas price trends and fuel economy, which affect shipping costs and profit margins, truck loading times in relation to the number of workers available, which affects the time it takes for the delivery to reach its final destination, how users interact with the company's app to track their packages, which affects the customer experience and the company's ratings, and whether users engage with marketing emails sent after they make specific purchases which impacts future and repeat sales. My point is each of these variables affects the way organizations harness data to transform decisions. Automating and adapting machine learning where applicable. The ability to unlock transformative information within data is a skill that businesses seek.
As you progress within this program, you'll discover how data professionals can make meaningful contributions to almost any organization by finding action-oriented solutions within data. All professions require a certain set of tools for success and data-driven work is no different. In this video, we'll open our analytics toolbox and look at some of the most common items. Before we begin, I wanna emphasize that each of the items serves their own individual purpose.
However, when used together, they help build and tell stories with data which can then inform, influence and impact business decisions. Programming languages are the first tools we'll investigate. They allow data professionals to work efficiently within and dissect large data sets. Most languages have been developed over time and each data professional has their own preferences. We'll mention two in this video that have become very popular for data analysis.
The R programming language and Python. R is a programming language that's used extensively by researchers and academics. It was my primary language during graduate studies in statistics and some people say that R captures the statisticians mindset.
I'd say there's something to that sentiment. If you're after implementations of the latest statistical breakthroughs, R is a great place to look, but it's used for more than statistics. You'll find many new technologies and ideas programmed with it. One of the best futures of R is that you can create complex statistical models from just a few lines of code. If you're curious about R or need a refresher, be sure to check out our Google Data Analytics Certificate also offered here on this platform.
This program teaches the Python programming language. It's a great choice for a few reasons. First of all, it emphasizes readability making it one of the easiest programming languages to learn and write.
Second, unlike R, Python wasn't born in the data community. While this might sound like a minus, it can also be a huge plus. In the modern world, data is used in increasingly creative ways, so this is a massive advantage to learning a programming language that's capable not only of handling the data side of things but can also be used to build and deploy the applications that data will be fueling. Although R was my first love, these days I find that I lean more heavily on Python because of its flexibility.
Python can perform a wide variety of data-related tasks, which makes it very popular among data professionals. If you're a novice or new to coding completely, Python is a very approachable language. It's formatting is visually uncluttered. It's one of the most beginner-friendly languages and it has enormous online communities and plenty of resources to help you if you get stuck. We will interact with Python within a web-based computing platform, also called Jupyter Notebooks, which allows you to run code in real time and helps identify errors easily.
To visualize the stories in the data, we're going to teach you how to share complex data through a graphical interface. Those who experienced our data analytics program will be familiar with a platform called Tableau. In this program, we'll take a more detailed look at how this powerful tool can help others understand the results of your analysis. Additionally, we'll look at effective communication in data-driven careers. At first glance, it might seem like less of a concern, but describing the sometimes complex processes of data analytics to non-technical stakeholders may be one of the most important skills a data professional can have. Since communication is something we all do regularly, it's easy to forget about the importance of how data professionals share and process data stories.
Our goal here is to strengthen the communicative skills that you already possess so that you can leave this program equipped to excel. In this course specifically and across other segments of this program, communication will be a key component that is directly tied to the work you'll do as a data professional. Programming languages allow data professionals to interact with and interpret data.
Visual data tools like Tableau enrich the stories within data with visual elements that bring attention to specific details, but the most important element of any story is the storyteller. That's you. Your prior experiences and knowledge inform your storytelling abilities and your distinct background is what will say to you apart from others in these roles.
Regardless of your eventual career path, remaining determined and developing the proper skills is essential to personal and professional transformation and the tools we're offering you in this program will also help you along the way. I'm thrilled to continue alongside you in your journey. The best is yet to come. I'll see you soon. Congratulations on completing the first part of this program.
You've officially begun your journey to new opportunities in the data field. Let's revisit what we've covered so far. First, we covered the basic logistics of what's included in the certificate. You met each of your instructors and we previewed some of the different course topics you'll encounter.
Next, we looked at the basics of data-focused work and some of the industries that are incorporating data insights. We also discussed the future of data-driven careers. In addition to exploring what it's like to work in the data field, we also discussed the data professionals toolbox and the skills this program will help you develop. Congratulations on your progress so far. I can't wait to see you in the next video.
As you know, this program asks you to complete a greater assessment at the end of each section and course, and now's the time to prepare for your first one. This assessment will effectively verify your understanding of key data analytics concepts. It will also help build confidence in your understanding of data analysis while identifying any areas where you can continue to improve. Assessments can sometimes feel overwhelming, but approaching them with a strategy makes them more manageable.
Here's a list of tips to set yourself up for success. Before taking an assessment, review your notes and the videos, readings and the most recent glossary to refresh yourself on the content. During the assessment, take your time, review the whole test before filling in any answers. Then answer the easy questions. Skip the ones you don't know the answer to right away. For multiple choice questions, focus on eliminating the wrong answers first.
Also, it's a good idea to read each question twice. They're often clues that you might miss the first time. If you start to feel anxious, calm yourself with some mental exercises.
One way to do that is by completing a simple math problem in your head or spelling your name backwards. This also helps you recall information more easily. Before you submit the assessment, check your work, but be confident. Sometimes people change an answer because it feels wrong, but it's actually correct. Your first instinct is often the best one. Finally, remember to trust yourself.
Often people know a lot more than they give themselves credit for. Everyone learns at different speeds and in different ways, but it's important to maintain your momentum, so take the time you need and when you feel ready, keep moving ahead. You've got this. Great to have you back. I'm so delighted to be your guide as you continue on your way to becoming a data professional. As you've been discovering, data can be used in many ways, but no matter how it's applied, the key thing to keep in mind is that knowledge is power, the power to improve your business, your work, your personal life and the world around you.
With all of the data surrounding us, there's just so much potential waiting to be unlocked. I'm so glad that you've chosen to learn more and to be a part of it. And speaking of your learning journey, in this section of the course, we'll start by finding out more about data careers. We'll explore different industries and examine some direct applications of data-driven work and we'll investigate where data careers are headed in the future. It's such an impactful and rewarding field and it just keeps getting better. I'm so excited for you to get started.
Let's go. Data professionals are so valuable to their companies. They determine which data streams are most important to specific business projects, challenges and initiatives. They identify key goals for the future and they give their organizations the ability to take meaningful action by re-imagining processes and improving operations. To do all of this, data teams require individuals with diverse skills, knowledge and interests. Therefore, they're countless different data focused roles, responsibilities, and project types which are further differentiated by the industries and businesses they support.
Among all of these possibilities, data careers can be loosely categorized into two complimentary types of work, technical and strategic. In this video, we'll investigate both. First, let's find out about the folks whose work requires a heavy emphasis on technical skills. Some examples of these professionals are machine learning engineers and statisticians. These people provide high effort solutions to specific problems. Through their expertise in mathematics, statistics and computing, they build models and make predictions using tools such as R and Python, they help their teams extract value from business data sets.
The result is a solution that has a direct positive impact. Another highly technical role is the expert data analyst whose work involves exploring vast and complex data sets to identify directions worth pursuing in the first place. They ensure that an organization's data science efforts are directed as efficiently as possible. Bridging the gap between other technical data professionals and the strategic work will cover shortly. Like most technical data professionals, you'll learn how to acquire, scale, organize, structure, and manipulate data so that it's packaged in a way that others can work with.
In other words, you'll know how to transform raw data into something useful for decision making. Okay, now let's consider data professionals on the more strategic side. These people include business intelligence professionals and technical project managers, to name a couple. Strategic data professionals use their skills to interpret information that affects an organization's operations, finance, research, and development and so much more. Their work aligns closely to the overall business strategy and involves seeking solutions to problems through data analytics.
In short, strategic data professionals maximize information to guide how a business works. Sometimes you'll find a company has roles that blend specialist technical knowledge with strategic data expertise often in unusual and very creative ways. Soon we'll learn more about some of these opportunities as well as the more specialized technical and strategic roles, and of course we'll discover some proven ways to tap into them as a data professional. Lots more to come.
Nowadays, it seems that data is generated everywhere. Computer functions have been integrated into a multitude of everyday technologies, smart home voice assistance, step trackers, TV streaming apps, even some coffee makers are connected. All of these touchpoints create data that businesses can use to understand trends and advance their products and services. And with every update, the ability to gather environmental and user data expands even further. Within this massive reserve of data is a wealth of untapped potential awaiting data professionals and the organizations they support. That's why these people are so in demand.
Companies need them to use data to refine business strategies, meet consumer preferences, react to emerging trends and realign internal efforts. Let's consider some examples of how data professionals use their expertise to transform industries. First, the world of big finance was an early adopter of the power of data science and with the way information drives this industry, it's easy to understand why. Data professionals help financial institutions assess investment risks, monitor market trends, detect anomalies to reduce fraud and create a more stable financial system overall.
Hundreds of millions of financial transactions occur in the financial world each day and data is part of each and every one of them. As another example, data analytics is key in healthcare and here the data benefits can actually be in lifesaving. For instance, the information collected by smartwatches is making a huge difference in the lives of many people. Sensors in these devices record biodata such as heart rate and oxygen levels, and of course all this information can be shared with healthcare professionals.
Together, the patient and the physician can better understand sleep trends, stress levels, and much more. Then individualized wellness plans can be created and modified for the patient's wellbeing. Plus, on a larger scale, data analytics is helping healthcare organizations process large amounts of clinical data, which supports the early detection of a health condition and leads to more precise diagnoses. Thirdly, data has a big impact in manufacturing. Data professionals predict when to perform preventative maintenance to avoid production line breakdowns, use data to maximize quality assurance and defect tracking and artificial intelligence models help respond to logistical issues and reduce delivery truck miles on the road, advancing key sustainability goals. And in a time when supply chains reach every corner of the world, data enables clear and near real-time communication with suppliers, retailers, and other network partners.
It also helps supply chains maintain optimal levels of inventory to avoid stockouts and empty retail shelves. Data professionals are also advancing approaches to agriculture. With data insights, farmers develop new ways to approach crop production, livestock care, forestry and aquaculture.
The inclusion of autonomous machinery, tractors and irrigation systems is improving harvesting technologies as well. If you'd like to keep learning about how various industries use data analytics, refer to the course resources on this topic. And here's a little piece of advice from me: don't miss an opportunity to learn from someone in real life. I love asking business owners, store managers and client support professionals about how they use data each and every day. Who knows, one of these conversations could open a door to a future opportunity for you. Recently, you've been learning about how businesses use data to guide decision making, answer questions and solve problems.
In this video, we'll investigate how nonprofits use data analysis to pursue their unique goals. Nonprofit groups are created to further a social cause or provide benefit to the public. As the name suggests, their main purpose is not about profit, but to foster a collective public or social advantage. There are some very rewarding and inspiring opportunities for data professionals in the nonprofit sector.
In particular, data can be applied in order to help these groups more effectively anticipate and respond to the greatest areas of need. For instance, maybe a US charity that provides bicycles for children would like to determine which neighborhoods are most in need. They could ask their data professional to access the US Census Bureau.
The professional would use their talents to navigate the Census database, identify key metrics and summarize findings with analyses and data visualizations. This report would highlight where there are larger numbers of school-aged children in need who would benefit from the resources of this program, and there you go. Data insights led to informed decisions about where this nonprofit can do the most good.
Now, nonprofits do more than use data. Many of them also collect it. As you likely know, public entities and government agencies can be excellent resources for useful data, and much of it is open data that's available for general use. As you likely know, open data is data that is available to the public. It's free to use and guidance is provided to help navigate the data sets and acknowledge the source.
While sourcing open data is a good way to interact with data on your own, there are other opportunities that enable you to refine your skills while helping others. Data volunteers contribute to many projects that help nonprofits benefit communities all over the world. To find out more, here are some organizations to check out. First, the Data Science for Social Good Foundation was launched at the University of Chicago back in 2013. In 2020, they trained forces with UNICEF to analyze various aspects of air pollution around the world to help monitor children's health.
DataKind launched in 2011 in New York City with chapters in the United Kingdom, Bangalore, San Francisco, Singapore, and Washington, D.C. This organization analyzes the cost of environmental cleanup in different underserved communities to guide restorative efforts. You can view both foundation's latest efforts through the links in the transcript for this video. Another option for putting your data skills to good use are hackathons. A hackathon is an event where data professionals and programmers come together and collaborate on a particular project.
The goal is to create a solution to an existing problem using technology. Some examples include developing better tools for predicting extreme weather events, creating tech to help elementary school kids learn important reading skills and identifying ways that community development groups can use their data to advance home accessibility and affordability. Volunteering your data skills to public projects is an excellent way to contribute to the greater good while gaining experience and networking with others in your field. Coming up, we'll take a deeper look at some data-oriented projects in the public sector and how they're making an impact around the world.
One of the most important responsibilities for those of us in data-centered careers involves how we protect our organizations, manage and protect data. This has a lot to do with communication exchanges between a company and its customers. As you've been learning, almost all communication generates data, whether it's a shopping receipt, confirmation of an order, or even earning customer loyalty points. And businesses have a big responsibility to their customers, especially when it comes to maintaining and protecting user privacy. Any data gathered from individuals or consumers is referred to as personally identifiable information or PII.
PII permits the identity of an individual to be inferred by either direct or indirect means. This includes things like biometric records, usernames and social security, or national identification numbers. Because this information is often associated with medical, financial and employment records, PII is sensitive and must be managed with great care.
After all, when someone's personal data is improperly handled, they become vulnerable to identity theft, fraud, and other issues. Recently, there have been great efforts to take a wider view of data collection practices and protect individuals. Industries are trending towards aggregate information.
This is data from a significant number of users that has eliminated personal information. By aggregating the data and removing PII, this protects people and gives them more control over their own data. Similarly, as more industries become interconnected, the amount of data available to them increases, and just as with aggregate information, the more data collected, the more likely it is that it will be representative of a wider population, rather than a single user. A key thing to keep in mind is that data gathering is a task managed by humans, and that process can be informed by different backgrounds, experiences, beliefs, and worldviews. These and other types of biases can affect the way that data is communicated and how the results are shared, which in turn can have an impact on business decisions.
Effective data professionals know that whether collecting, analyzing, interpreting or communicating sensitive data bias should always be considered, so be very careful when interpreting data where there is a clear source of bias and be on the lookout for subtle biases as well. In addition to thinking through bias in the data, data professionals should also try to emphasize that there can be a multitude of possible interpretations for every data insight. So the main trick is avoid jumping to conclusions until you've really done your homework. One method of addressing bias is to make sure that the data that you are working with has the same characteristics as the greater population that you're interested in.
In data analytics, this is called a sample. A good sample is a segment of a population that is representative of that entire population. Here's an example. A clothing company is analyzing sales in their highest growth market. They want to determine what color shirts will be most popular in the upcoming season. One person notes that red and blue shirts accounted for 80% of their sales in this market over the past three months.
This is a big number, so they suggest ordering lots of red and blue shirts, but another person points out that the local sports teams colors are red and blue, and this team had recently won a championship. It's very likely that sales of red and blue shirts will have spiked as consumers purchase tees to support the local team. Plus, they note that although this market is high growth, it only represents 40% of the retailer's total sales. With all this information in mind, decision makers at this retailer, instead, choose to evaluate color popularity over a full year and across all markets. This will provide a much more complete picture. We'll investigate more about bias later in this program, and as you progress, you'll discover many more strategies for ensuring that you're aware of bias and proactively working to counter it in all of your data work.
When investigating a possible new career path, one of the most important things to consider is its outlook and potential for growth. Predictions about careers related to data analysis show that there is no shortage of need for professionals in this field. Over the last decade, data focused careers have searched. According to estimates by LinkedIn the data science field grew by over 650% between 2012 and 2017. Many experts believe that we have not yet seen the full potential of these careers.
In fact, the US Bureau of Labor Statistics stated that data science is one of the fastest growing career fields in the United States projecting a 30% increase over the next decade. Among the data science professions, one of the fastest growing is artificial intelligence and machine learning, and we've seen significant advances in these areas in recent years. At its core, artificial intelligence, or AI, is the development of computer systems able to perform tasks that normally require human intelligence. Thanks to growth in the data sciences, AI is now becoming more commonplace. These technologies will continue to evolve and provide more accurate results and richer insights.
And as AI increasingly becomes an essential component of data work, it's important to be aware of the human bias that can be imprinted within your work. To counter this, organizations benefit most from building diverse teams of professionals from different backgrounds and different life experiences. Incorporating a wide range of perspectives and worldviews promotes wider representation and yields more accurate results.
As we study the future of the data professions, I wanna emphasize that data professionals have yet to realize the full potential of artificial intelligence. As these types of technological innovations continue to evolve, we can expect that organizations will grow and adapt their business practices accordingly. With wider and wider adoption of data analysis techniques, the most likely area for growth is in specialization and we expect to see further subdivision of roles within data focused teams. Ultimately, what I want you to keep in mind is this: the world is generating more and more data every year, so it's reasonable to expect labor that extracts business value from it to be able to earn its keep.
More data means more demand for the three main activities covered by the data professions: statistical inference, machine learning, and data analytics. So those skills will stay very relevant, though their names might evolve over time. In addition, constant innovation in the field offers you the opportunity for perpetual learning, growth and development.
As you may already know, being a data professional means that your growth and success in this field depend on a desire to keep learning. In fact, that just might be the reason you enrolled in this program and for that I'm so proud of you. Continue to explore opportunities to evolve throughout your career. Be proactive in acquiring new skills, keep growing, and you will always be ready for the future. In this section of the course, we explored many different facets of data careers. You learned that data professional is a broad term that encompasses different roles and responsibilities in the data space.
You discovered that the work we do in this field involves countless possibilities, such as determining important data streams, identifying and focusing on future business goals and re-imagining internal and external processes. You also thought about some of the ways that organizations are being transformed by data professionals and how these talented individuals use their skills to positively impact communities around the world. You've come so far already, but there is so much more to learn. Thanks for joining me on this exciting exploration and I'll catch up with you again soon. Welcome back. I'm really excited to share this section with you.
We'll start by looking at some of the skills needed in the data field today. We'll look at what happens after you land a data position and what to expect in those first few weeks on the job. We'll investigate some of the roles within the data professions and take a closer look at the general categories that you'll encounter. Then we'll explore the importance of networking and building relationships within an organization.
We'll also look at the responsibilities of different data professionals, so let's get started. See you in the next video. All data professionals share a love of data and a desire to solve problems.
While wearing their analytics hat, data professionals lay out the story that they're attempted to tell and then they poke it from several angles with follow up investigations to see if it holds water before bringing it to their decision makers. In doing so, they rely on their programming and investigative skills to guide others towards informed decisions. Data professionals also combine a knowledge about how to do practical tasks with an awareness of what makes communication and collaboration successful. Later, we'll dig deeper into the elements of communication and discuss the ways communication enhances and structures your work as a data professional. For now, let's examine some skills and attributes that are applicable across data-driven careers. Working in data analytics requires a mix of business sense and knowledge in gathering, manipulating and analyzing data.
Our goal is to prepare you to develop the competencies needed to succeed. Let's start by discussing some interpersonal skills. Often these are referred to as people skills. They focus on communicating and building relationships.
Interpersonal skills are critical. In this field, there's a high degree of interaction between stakeholders. This is especially relevant now with team members often working collaboratively across the globe. Very often, work conversations are the starting point and the fuel that drives projects, and because of the cyclical processes within data analysis, communication is always ongoing. Another important skill is active listening.
This means allowing team members, bosses, and other collaborative stakeholders to share their own points of view before offering responses so that each exchange improves mutual understanding. You can actually practice active listening. Next time you speak with someone, put extra effort into listening beyond their words, focus on what they're trying to communicate. Your listening and communication skills will play a huge role in helping you capture effective insights and informed decisions.
We'll take a closer look at communication a little later in this course. There are other things you'll need to consider. As a data professional, you'll search for information hidden within large amounts of data by applying critical thinking skills. Along the way, you'll investigate the connections between a variety of different data sources as you search for trends and indicators. Think of yourself as a data detective.
Project data can come directly from your organization or from other sources. You might be lucky and receive a well formatted spreadsheet or database, but quite often you will need to prepare the data to get started. This process is known as data cleaning. This is where the data is reorganized and reformatted. The goal is to remove anything that could create an error during analysis. This process includes tagging and consolidating duplicates, irrelevant entries, structural errors, and empty space.
Once you have everything in the proper format, you can then filter out unwanted material. Now your data is ready to be analyzed. It's time to look for trends and tendencies. Often it's very helpful to render the data visually to reveal additional insights through charts, dashboards, and reports. Graphic tools will be very useful in identifying patterns as well as in sharing information with others.
You will explore this in greater detail later and have opportunities to practice compiling visualizations too. You'll also learn about more advanced skills like building models and machine learning algorithms. These tools will help you and other data professionals assess information accuracy, analyze specific data segments, and predict future business outcomes. Your hard work will assist leaders and other decision makers in your company providing them access to a rich variety of perspectives on different sets of information. With demand for data analytics increasing across all types of companies and businesses, you will likely find opportunities in an industry that you are personally interested in. Next, we'll take a look at working in the data field.
You can learn a lot about a career by looking at job postings. If you've searched for opportunities in the data space, you may have noticed different data related job titles with similar responsibilities or postings with similar titles, listing different responsibilities. Here's an example. At one company, the role of data analyst will focus on using statistics and models to craft insights that inform business decisions. Another job with the same title at a different company may focus on optimizing the tools and products that automate analytical processes.
One reason for these inconsistencies is that data tasks and responsibilities are dependent on an organization's data, team structure and how they make use of insights and analytics. As such, some organizations choose to be very specific with responsibilities. Others leave job tasks quite broad in scope. That's why this program refers to the field as a career space. With that said, when you're comparing positions that have similar titles, I encourage you to classify them based on the skills used in their day-to-day activities.
Two of the most common titles are data analyst and data scientist. These can cover a wide range of job responsibilities, many of which you'll gain experience with in this program. Traditionally, a data scientist was expected to be a three in one expert in data analytics, statistics and machine learning, but not all employers use these conventions when writing their job descriptions. Generally, any role that includes analytics expects candidates to be able to function as technically skilled social scientists looking for patterns and identifying trends within big data sets.
Also, they develop new inquiries and questions as they uncover the stories inside their data. Their hard work can help steer a company's future actions and guide decision making. They allow their organizations to keep a finger on the pulse of what's going on in the business, interpreting and translating key information into visualizations such as graphs and charts, allowing every stakeholder to understand their findings.
At times, they may be tasked with creating computer code and models to recognize patterns in the data and make predictions. When you investigate job postings, you'll encounter other titles with similar responsibilities. For example, junior data scientist, data scientist entry level associate data scientist or data science associate. All of these roles include a mix of technical and strategic skills to help others make informed decisions. In your career, you might encounter other professionals in roles that use data and analytical skills.
Some of these may overlap with the skills you will learn, but these roles are specific to certain tasks or are supervisory positions. Let's take a look at a few. Data scientists depend on systems within their companies to collect, organize, and convert raw data.
Designing and maintaining these processes are some of the most important responsibilities of a data engineer. Their goal is to make data accessible so that it can be used for analysis. They also ensure that the company's data ecosystem is healthy and produces reliable results. These positions are highly technical and typically deal with the infrastructure for data usually across an entire enterprise. You also need to have the ability to get data before it even makes sense to talk about data analysis. Most of the technical work leading up to the birthing of the data may comfortably be called data engineering and everything done once some data have arrived is data science.
Similar to how a data engineer oversees the data infrastructure, there are data roles that manage all aspects of data analytics projects for a company. Insight managers or analytics team managers often supervise the analytical strategy of the team or of the organization as a whole. As a data analyst, you will likely report to someone working in this capacity. They're often responsible for managing multiple groups of customers and stakeholders, and they're often a hybrid between the data scientist and the decision maker.
Since this combination of skills is rare, these positions are often more difficult to fill. This role can have other titles like analytics team director, head of data or data science director. You may encounter another job role in your scan of job postings, business intelligence engineer or business analyst. This role is highly strategic, focused on organizing information and making it accessible.
BI analysts synthesize data, build dashboards and prepare reports to address specific needs for a business or requests from leadership. If you're interested in learning more about business intelligence and its opportunities, I encourage you to look into the Google Business Intelligence Certificate. Now that you have some idea of the roles found within the data analytics career space, we'll begin to take a closer look at how data professionals function within their larger organizations. Compared with many other professions, the data career space is relatively young. This application of data-driven work in organizations has grown exponentially in the last several decades, which means there are many different opportunities and much job security for you in the future. Now that organizations have the technical capacity to take on their own data focused work, they're looking for people like you with the right skills to fill these jobs.
Traditionally, companies have filled jobs in the data career space with those from computer computer engineering backgrounds or from statistics. Increasingly, there's been a shift towards de-emphasizing engineering and instead, promoting analytical skills. These skills can be learned in different forums like the program that you're currently enrolled in. Let's look at a scenario. Let's say that an enthusiastic and enterprising person, that's you, is starting a new position at a company as a data professional.
Your company is a recognized leader in its industry. Its workforce spans the globe and you are its newest member. It's your first day on the job and you are ready to start working.
During your orientation, your company grants you systems access and onboarding documentation. You're starting to have a clearer picture of how information is generally shared with employees. You still have many questions about the responsibilities of the position.
Later, you watch a video from the quarterly review meeting led by a company executive. Watching the presentation, you get insight into the quarterly budget, recent client interactions and some general information on an upcoming project. You now have a broad understanding of the company.
At this point, you still lack details about your specific responsibilities. During your first week, you're invited to a virtual meeting of the data professionals involved on the project that you've been assigned to. As each data professional outlines their job responsibilities, you take note of the differences among them. After each participant speaks, you begin to realize that not all data tasks are universal and that many data professionals end up adapting to meet the needs of the current project and the needs of the data.
When you're new to a job, I would discourage you from over specializing immediately. Instead, taking on a variety of tasks within a project is a great way for newer data professionals to continue developing their skillset. As a member of a larger group of data professionals, you're able to observe and learn from your team members. Once the analytical process is complete, the results of the project will need to be shared, allowing everyone in the organization to have access to the information. This includes building user-friendly interfaces and communicating the findings to different departments.
Working for a large company means that there is a good chance that you will be dealing with vast amounts of information. This will require more work than a single data professional can reasonably provide. Because of this, you might encounter scenarios where organizations have created teams of data professionals.
Throughout the rest of this section, you'll take a closer look at how complex organizations are incorporating data professionals through data teams and the division of responsibilities within these teams. - Hi, I'm Tiffany and I lead teams focused on building AI responsibly here at Google. I've served in the United States Army, worked as a consultant and have worked as a program manager in privacy and machine learning fairness. Data and having a rich understanding of data has always been an important part of my job.
Today, we have more data available to us than ever before, and it's important to be able to derive insights to help decision makers make the best possible decisions. I'm so glad you're here and I really hope this program is giving you all kinds of new possibilities to think about. You've already learned so much. We've covered the basics of data-driven fields and looked at career roles, how data professionals are being used by different industries and how those in the field can make a valuable contribution. You're gaining a vast range of knowledge and skills, which is going to be extremely valuable as you prepare to join us in the amazing field of data-driven careers. At this point in the program, I encourage you to take some time to reflect on how your experiences so far are setting you up for a great career, and one way to do that is by enhancing your current online presence.
In the Google Data Analytics Certificate, we covered numerous job related materials including how to create an effective resume and LinkedIn profile. This video is about improving your existing career assets. Those of us who were involved in the Google Data Analysis Certificate always love receiving learner feedback, especially when it has to do with someone else's professional success. I remember one person who took the initiative to refine her LinkedIn profile as soon as she began the program. She noted that she was currently working through her program and she added to her profile many of the technologies she had become familiar with.
Well, not long after, she saw an advertisement for her dream job, even though she was early on in her DA education, she decided to apply for it and she got it. The hiring manager told her that the fact that she had familiarity with those data tools really set her apart from other candidates. There are tons of stories just like this one that proved the value of having a compelling and professional LinkedIn presence. So let's get into that now. A professional online presence enables you to better connect with others in the field.
You can share ideas, ask questions, or provide links to a useful website or an interesting article in the news. These are great ways to meet other people who are passionate about data focused jobs. Even if you're already part of the community, strengthening your network makes it even more dynamic. LinkedIn is an amazing way to follow industry trends, learn from thought leaders and stay engaged with the global data analytics community, and of course, it has job boards and recruiters who are actively looking for data professionals for all sorts of organizations and industries.
So it's a good idea to always keep your profile up to date and to be sure to include a professional photo. Beyond that, consider including a link to some of the relevant projects you've done in data analytics such as the portfolio project you'll work on during this program. As you continue expanding your online presence to represent the work you're doing in data analytics, the connections you make will be an important part of having a truly fulfilling networking experience. Plus, there are also many rewarding in-person networking opportunities, which will explore soon. See you then.
Recently, you learned about the value of maintaining a professional online presence and connecting with others in the data field. As I noted, there are many professional networking sites such as LinkedIn that are well worth your time and involvement, but here's something that many people don't realize. Some of the best opportunities are never actually shared on a networking site.
