Data analytics is the study of analyzing raw data to draw inferences and gain insights. It is beneficial for businesspeople and students looking to operate their own company as it helps in obtaining consumer insights from a data set. There are four types of data analytics: descriptive analysis, diagnostic analysis, predictive analysis, and prescriptive analysis. Descriptive analysis provides historical insights, while predictive analysis makes predictions about future events. Diagnostic analysis delves deeper into the data to identify underlying causes, and prescriptive analysis determines the optimal course of action. Companies choose different types of analytics based on their decision-making process.
