Compare numeric outcomes with confidence intervals and effect sizes. Two independent groups only. Welch t test with Student t distribution, Welch degrees of freedom and 95% confidence interval for the mean difference. Hedges g uses pooled standard deviation and small-sample correction. Requires at least 2 observations/group; paired, clustered or repeated measurements violate assumptions. Not a binary conversion A/B test.

Prepare the input

Compare numeric outcomes with confidence intervals and effect sizes.

CSV, TSV and arrays of scalar JSON objects are supported. Identifiers stay text. Empty cells are missing by default; add special missing tokens only if their meaning is certain. Use the sample to inspect the exact workflow.

Keep the useful output

Review the summary and result records. Transformation tools retain separate change, rejected-record or diagnostics datasets where relevant. Choose the dataset before exporting; a report and a cleaned dataset serve different purposes.

CSV exports protect formula-like text. JSON keeps data portable without making an Excel workbook. Reports and editable backups may contain private source values; download only what you intend to share. No automatic account storage or server processing is used.
