Can someone define aggregate data and explain its importance? or How would you define aggregate data

Wow, thanks everyone! This totally clears things up—especially the raw vs. aggregate distinction. I messed around with PivotTables in Excel like some of you suggested, and it’s way easier to see trends now.

Quick follow-up: When should you *not* use aggregate data? Like, are there cases where the individual details matter more?

(Also, Google Analytics is a game-changer—thanks for that tip!)
