What is Data Analytics?

At its core, data analytics is the process of examining raw data to uncover patterns, trends, and valuable insights. It involves collecting, organizing, and analyzing data using statistical methods, algorithms, and software tools to solve problems and inform decisions.

Types of Data Analytics

1. Descriptive Analytics: Answers What happened? by summarizing past data.
   • Example: Monthly sales reports or website traffic analysis.
2. Diagnostic Analytics: Answers Why did it happen? by identifying patterns and causes.
   • Example: Root cause analysis for a sudden drop in revenue.
3. Predictive Analytics: Answers What might happen? by forecasting future outcomes using historical data and machine learning models.
   • Example: Predicting customer churn or stock market trends.
4. Prescriptive Analytics: Answers What should we do? by providing actionable recommendations based on predictive insights.
   • Example: Optimizing inventory based on sales forecasts.
