What is Data Analytics?
Most businesses are constantly collecting data, but this data is meaningless in its raw form. This is when data analytics enters the game. Data analytics is the process of analyzing raw data to derive meaningful, actionable insights that can subsequently be utilized to inform and drive smart business decisions.
A data analyst will take raw data, arrange it, and then analyze it, changing it from unintelligible statistics into cohesive, understandable information. After interpreting the data, the data analyst will share their findings in the form of suggestions or recommendations for the company’s next steps.
Data analytics allows you to make sense of the past and predict future patterns and behaviors; rather than relying on guessing, you can make informed decisions based on what the data is showing you.
Armed with data insights, businesses and organizations can gain a much deeper understanding of their audience, industry, and firm as a whole—and, as a result, are much more positioned to make decisions and plan forward.
