 Introduction to Data Analytics – A Beginner’s Guide to Making Data-Driven Decisions

In today’s digital age, data is everywhere—from the clicks on a website to transactions in a store, to the posts on social media. But raw data alone doesn’t provide value. The true power of data lies in analytics—the ability to transform data into meaningful insights.

This is where the "Introduction to Data Analytics" course comes in. Designed for beginners, this foundational course helps you understand how to work with data, ask the right questions, and make informed decisions across industries.

 What is Data Analytics?

Data analytics is the process of collecting, cleaning, analyzing, and interpreting data to extract useful information, detect patterns, and support decision-making.

There are four main types of data analytics:

Descriptive – What happened?

Diagnostic – Why did it happen?

Predictive – What will happen?

Prescriptive – What should we do about it?

This course primarily focuses on descriptive and diagnostic analytics—the building blocks of data fluency.
