Need to remove duplicates before crunching numbers? Prep the dataset with the duplicate remover or convert CSV exports with the CSV ↔ JSON converter first.
Where these stats shine
- Marketing ops compare score distributions, then pivot to the percentage calculator to show before/after lifts.
- Finance teams analyze revenue cohorts here before testing growth scenarios in the investment return calculator (or their spreadsheet of choice).
- Product managers calculate medians and IQR to spot outliers, then track timeline impacts using the duration calculator.
