Can someone explain the meaning of aggregate data and why it's important? or What exactly is the mean

Kinda like how a report card summarizes your grades, aggregate data summarizes raw numbers. It’s not about each quiz score but your overall performance.

Companies use it to make decisions—like whether to open a new store based on regional sales averages, not every single receipt.

For tools, Excel’s PivotTables are beginner-friendly. SQL’s aggregate functions (SUM, COUNT, etc.) are must-knows.
