Features
Guided descriptives in Excel — not a dump of every ToolPak number, and not a Dist or Forecast clone.
Data fingerprint
Type, n, missingness, skew (G1), excess kurtosis, Tukey flags, grouping, and a series-like hint — before any recommendation.
Which-summary rank
A documented rule picks location and spread among candidates on this sample. Mean and SD stay visible for comparison when they are not the pick.
Evidence plots
Histogram, box plot (grouped when you compare), and ECDF — the same charts embed in the PDF.
Nested tooltips
IQR, Q1, SD and the rest expand in the pane. Essays live here on whichstat.com, not in the task pane.
Statistic DNA + Learn
When to use, when to avoid, assumptions, and Student / Analyst / Formal shorts for every recommended summary.
Watermark-free PDF
Client-side letter report. Optional footer default on: Prepared with WhichStat for Excel · whichstat.com.
Offline & free
No account. No Pro plan. Raw samples are never uploaded. JSON export strips the raw vector.
Seven languages
English, Turkish, French, Spanish, German, Italian, Dutch in the add-in. This site is English first.
Sibling handoff
Need a generative distribution? WhichDist. Need a forecast? WhichForecast.
Versus Excel Data Analysis ToolPak
Honest, not a dunk. ToolPak is useful; it is not a guided which-summary workflow.
