Data analytics, in simplest terms, is the collection, transformation, and organization of data to draw conclusions, make predictions, and inform business decision-making. Data is obtained and analyzed in three stages. Data collection includes creating a method of obtaining the information requested. Data can be collected using various techniques like surveys or interviews. This information is stored until the second stage, processing and organization begin. During the second stage, individuals review the data and ensure there are no errors or missing information; this is called cleaning the data. Finally, once data is cleaned, analysis moves on to the final stage of data analysis and visualization. The data is reviewed for patterns, insights, and trends during this final stage. Once analyzed, it is time to present the information visually to explain your findings. The process can be tedious and require a lot of time, but many feel accomplished when finding a solution to a problem or answer to a question from the data collected.
Data analytics is not a new concept. The concept has been around since the 1950s, and the term was often used to discuss business trends. Most businesses use data analytics to make well-thought-out business decisions, but it is most commonly used in health care, retail, manufacturing, and banking. Data can be used to future-proof the business, improve productivity, mitigate risk, help stakeholders make better business decisions, and help organizations reach their goals. Simply put, data analytics is the process of analyzing data trends; there are four primary types of data analytics to consider when discussing this topic.
- Descriptive analytics describes business outcomes and can help track successes and failures. It requires the collection of relevant data, data processing, analysis, and visualizations. Many consider this looking at “what” is happening.
- Predictive analytics is used to predict what will happen in the future. Many consider this looking at “what” will likely occur.
-
Diagnostic analytics helps answer questions about why things happen. It uses the findings from descriptive analytics and then takes things a step further by investigating trends and outcomes. Diagnostic analytics is considered looking for “why” this is currently happening.
- Prescriptive analytics can help answer questions about what should be done using insights from predictive analytics. This is considered looking at “what” needs to happen.
Each type of data analytics provides businesses with the additional insight they need to make the best decisions for their business success. While each has its own goal, some are interconnected and rely on each other to gather sufficient information.
What Can You Do with Data Analytics Training?
Many people have chosen to get into data analytics because it is becoming increasingly in-demand. The increased popularity of data analytics provides job security for many because of the growing demand.

Various jobs are available that can use the skills learned in a certification or course. Skills can also be used to improve or enhance customer experience with a company by identifying areas of opportunity to streamline processes and increase productivity.
Data analysis improves efficiency by reviewing data that provides insight into key business success drivers. Someone well-versed in data analysis is well-suited for specific Risk Management positions. Risk Management helps businesses identify potential risks and develop strategies to decrease the chances of risks occurring. Finally, some roles can use analytics to help enhance the customer experience. Using business data, an analyst can find what strategies lead to the business’s success and how to improve existing products and services. Data analytics training can be used in various industries and roles, so investing in the training is worthwhile, even if you are still trying to figure out what to do with those skills.
What Will I Learn in a Data Analytics Class?
Data analytics courses can range from beginner to advanced. Depending on how detailed the course is, participants will learn a certain amount in the class. However, some basics will likely be covered during a data analytics class to ensure students are knowledgeable and set up for success.
Statistics
Statistics collects, analyzes, interprets, and presents numerical data. Statistics is a skill that translates well and can be used everywhere, not just in data. However, data analytics is heavy in statistics, meaning courses will provide students with various levels of detail on statistics. It helps extract meaningful data that can be used to draw conclusions. Statistics is also used to create probability distributions; this helps manage which statements help predict future events. Statistics is vital in data analytics because it allows analysts to understand what's happening and provides insight for businesses and other clients. Statistical methods also help identify patterns and areas of improvement, which helps develop strategies.
Data Visualization
A large part of data analysis is data visualization. Data visualization represents data using charts, tables, infographics, plots, and graphics. Data visualization is imperative for data analytics because it showcases the work done. It is a great way to display ideas in a way that all decision-makers can understand. Some additional and standard visualization techniques include pie charts, area charts, scatter plots, and histograms. Most data analytics classes will likely cover the most common data visualization methods. Many courses will also teach students how to use Java and CSS, valuable tools in the data industry.
Programming

Running a data analysis can yield a lot of information—some pertinent in the moment and others not as crucial at the time. Many find it challenging to manage the amount of data received while also determining what is useful and storing the data that is not needed. It can be overwhelming for most people. The best thing to do is to take your time and start with one piece of data at a time. As you work through the data piece by piece, you will know what needs to be used at the time. Storing data securely and keeping it for later projects is just as crucial as determining when and how to use what you have. With more experience, the feeling of being overwhelmed should decrease as you develop a system for how to best manage your data.
How Long Does It Take to Learn Data Analytics?
When wondering how long it takes someone to learn data analytics, the simplest answer is: it depends. Coming into data analytics, the time it takes you to learn the basics can depend on how much knowledge you have before starting your program. Some individuals begin learning the ins and outs of data analytics with some understanding of data, statistics, or even problem-solving with numbers. This could be a significant advantage and decrease the time it takes to learn. When you start a program or explore data analytics, foundational education about the subject is essential. This means understanding what data analysis encompasses and learning the skills to make you competent in an entry-level position. This means understanding its core concepts, learning how to analyze data, and grasping how to explain your findings in a digestible way. Entry-level competence can take a few months as you become more comfortable and improve your skills.

Should I Learn Data Analytics in Person or Online?
Nowadays, convenience is essential for anything, including learning opportunities. With the current increase in popularity of online classes, some are on board with taking classes this way, while others tend to stick with the tried and true method of in-person learning. When deciding between online learning, in-person, or even an asynchronous option, despite what might be popular right now, it’s important to consider which method supports your learning style and is realistic for you. First, let's consider an asynchronous option or a self-paced-style course. Asynchronous classes allow for independent learning without being in a live course. Assignments typically still have assignment deadlines and a course end date, but there is no live instructor; lectures are usually pre-recorded. Asynchronous is ideal if you need flexibility and want to work at your own pace. Depending on how well you understand it, you can spend more or less time with a particular lesson. It can be challenging if you struggle with deadlines and procrastinate. An asynchronous course removes the additional level of accountability by having weekly classes, which can be difficult for someone who needs more time to focus or becomes easily distracted. You can still access your instructor via email or virtual office hours, so asynchronous does not mean you are entirely alone.
Live online classes are classes taught by a live instructor with classmates but in a virtual space. Online courses offer a great amount of flexibility because you can attend the class anywhere. There are no concerns about being stuck in traffic or out of town during class time; simply log in from anywhere and be ready to learn. Many people love this feature because it feels less restrictive of your time. Additionally, you save time because there is no commute. Online classes mean not worrying about parking and walking across campus to your next class. This saves you time and money. Finally, online classes are open to everyone, which means your classmates can be from anywhere and give you the opportunity to broaden your network by meeting people outside of your city and potentially outside of your state. This global networking opportunity can make your learning experience more enriching and diverse.
On the other hand, online courses can make it difficult to network with classmates. Spending time online versus in a classroom takes away from some of the organic conversations that can take place with classmates and instructors in the downtime before class starts. For many, this is where networking and building community can happen. Also, taking a class online typically means you need the software and other tools necessary for the class. In-person classes can offer a lab with specific programs you might need already loaded on the computer. While purchasing the program you're learning could be an investment, if you are taking numerous courses, this can become costly.
Finally, there's the traditional in-person course. Many prefer in-person courses because of the structured environment they offer. Students know they are in the classroom at a particular time and have that time set aside and dedicated to learning. This structured environment can help you prepare and focus better because you have the expectation to be present in class. Also, in the classroom, you are less likely to be distracted by your phone, TV, others living in the house or wherever you are taking the course, and it prevents multitasking during class time. Finally, during an in-person class, it can be easier to ask questions of the professor and your peers because you are all in the same room together. In-person classes can limit your flexibility because you are expected to be in class; this can be challenging for some. Also, in-person classes can be limiting. While online courses are available worldwide at a variety of locations, when selecting an in-person course, you have to consider the feasibility of your commute. Regardless of what you choose, there is a form of class that can accommodate the needs of every learner.

Some soft skills are not necessarily taught in courses but can be learned along the way and are just as vital as technical skills. Improving your communication skills can help improve your work as a Data Analyst. Improving communication skills can happen while working on a team in an unrelated field. Consider any areas of opportunity or feedback you receive related to communication as ways to improve these skills. Extracting data is one thing, but clearly communicating findings to other, less technical team members is just as important. Paying attention to detail is another essential skill. As a Data Analyst, you must be able to find answers and notice things that others might miss. Attention to detail can help you limit mistakes and stay on top of the data. This could look like finding a method that works for you such as keeping track of projects or staying organized with a planner. Being organized and having a system is a great way to notice those details that are out of place and catch them before they cause further complications.
