1. Types of Analytics

Key Concepts & Definitions

  • Descriptive analytics: The process of analyzing data that has already occurred to summarize and understand past events, providing insights into what has happened. It involves techniques like calculating averages, medians, modes, and measures of spread (variance, standard deviation).
  • Predictive analytics: The use of mathematical and statistical models to analyze past data in order to predict or classify future events. It involves building models that can forecast outcomes based on historical patterns, applicable to both numerical and categorical predictions.
  • Prescriptive analytics: The process of using data assets as a guide to influence or change future outcomes. It involves creating data-driven solutions to control or optimize events, guiding decision-making to achieve desired results.
