What is Data Analytics?
Data analytics involves the process of collecting, cleaning, analyzing, and interpreting large volumes of data to extract meaningful insights that help organizations make data-driven decisions. Data analysts use various statistical techniques, tools, and algorithms to identify trends, patterns, and correlations in data.
Data analytics can be broken down into four major types:
- Descriptive Analytics: Summarizing historical data to understand past behaviors and trends.
- Diagnostic Analytics: Understanding why certain events happened by analyzing data and identifying relationships.
- Predictive Analytics: Using statistical models and machine learning to forecast future trends and behaviors.
- Prescriptive Analytics: Recommending actions based on the results of the analysis to optimize business outcomes.
