ExplainStats adds a complete statistics toolkit to Google Sheets™, and it tells you what your results mean.

Select your data, choose an analysis (or let the Assistant choose it) and click Run. ExplainStats writes a clean results table into your spreadsheet, draws the chart, checks the assumptions and adds a plain-language interpretation you can understand and reuse.

WHAT MAKES IT DIFFERENT
- Which-test Assistant: say what you want to do and select your data. ExplainStats checks normality, outliers and equal variances, picks the right test (for example Welch's t-test, ANOVA with Tukey, or Kruskal-Wallis) and explains why.
- A plain-language interpretation under every result: what the p-value means, how big the effect is, which groups differ.
- A ready-to-paste results paragraph and an APA-style line for your report or thesis.
- Show the steps: rebuilds the calculation as live Google Sheets™ formulas, ideal for learning and teaching.
- Four languages: English, French, Spanish and Portuguese.
