What is Data Analytics

Data analytics involves examining datasets to draw conclusions about the information they contain. This process uses statistical analysis, computational techniques, and visualization tools to identify patterns and trends.

The field encompasses descriptive analytics (what happened), diagnostic analytics (why it happened), predictive analytics (what might happen), and prescriptive analytics (what should be done).

Modern data science combines programming, statistics, and domain expertise to extract meaningful insights from complex datasets.

Essential Skills to Master
