What is Data Analytics?

Data analytics is a broad term that describes the various techniques used to analyze raw, unprocessed data so that relevant insights and trends can be extracted. Organizations then use this information to make more informed, data-driven decisions. The data analytics process includes gathering data, organizing them, and performing statistical analysis on these numbers. Once the analysis is complete, the Data Analyst offers predictions that can inform the company’s next steps.

Each day, an estimated 2.5 quintillion bytes of data is created. This number is expected to grow as more organizations embrace technological advances and expand their online presence. However, until these data are analyzed, they are just numbers. A Data Analyst’s job involves combining computer programming, math, and statistics to interpret these numbers and transform them into actionable insights that they can share with various stakeholders in their organization.

The field of data analytics has many real-world applications across industries and professions. At the core of the data analytics process is the goal of using data to make better decisions. Companies rely on the data's insights to make more informed business decisions, which can help their organization grow, increase revenue, or better serve employees and customers.

Data analytics can help with marketing campaigns by eliminating the bulk of the guesswork in planning, creating content, and developing products. It also provides an overview of customers, which can help organizations better meet their needs. By better understanding your audience and what they want, targeting them with more pointed marketing initiatives and campaigns is easier.

Another widespread use of data analytics is to improve customer service. When data is analyzed, it reveals important insights about customers, which makes it possible to offer them more personalized service. Data can provide information on how customers prefer to communicate, what interests they have, what concerns they hold, and what products they look at most often. In addition, having data stored in a central location allows an organization’s customer service team to be on the same page as their marketing and sales teams.

Another use of data analytics is to improve the efficiency of operations within an organization. Data can reveal weaknesses in operations, as well as opportunities to streamline various processes. This not only helps the business perform more efficiently but can save money over time. For example, if you have a clearer idea of what your target audience is looking for, you won’t need to waste time and resources designing ads or writing content that doesn’t directly target their interests. This leads to less wasted money, as well as better campaign results.

How to Decide Which Online Learning Option is Best for You

Because so many online learning options are available for those interested in studying data analytics, it can be challenging to know which one is the best match for you. Unlike paid data analytics programs that often cover similar core material and provide learners with the same learning incentives, free online courses differ much more in content and quality. It’s helpful to ask yourself the following questions to decide which class is the best for you:

  • Does it provide the appropriate level of training? Those new to data analytics may be looking for more of an overview of the field rather than instruction on advanced SQL querying.
  • Is the material relevant? The field of data analytics is rapidly evolving, with new technologies and innovations being introduced all the time. This is why a video posted three years ago may no longer be relevant. To ensure that you receive instruction on the most up-to-date software and tools available, it’s important to consider how recently the video was created and if it has been updated to reflect recent advancements in data analytics.
  • Does it cover the content you want to study? Whereas some online videos provide a basic overview of data analytics, some short online courses focus on specific topics. This means you will want to select a video or combination of videos and tutorials covering the material you need to learn.
  • Does the class provide both theory and practice? Simply watching a lecture or reading a long text on data analytics theory isn’t the most effective way to learn data analytics. Instead, combining hands-on activities that combine theory with practice can lead to better retention. Choosing a learning option that combines activities with instruction leads to better learning outcomes.
