Data analytics means studying data to find useful information, patterns, and insights.
Every time you watch a YouTube video, use an app, or buy something online, data is created. Data analytics helps turn that data into knowledge — showing what people like, how they behave, and what decisions should be made.
In simple words, data analytics is the process of understanding the story hidden inside numbers.
