Tool guide
Statistics is a four-panel workbench for a sample of numbers. Descriptive summarises one column — mean, median, both standard deviations, SEM, CV, quartiles, shape and IQR outliers — and draws a histogram; Auto EDA adds a five-number summary, a Jarque–Bera normality note, per-column histograms, correlation pairs and plain-language suggestions, and reads NA as missing. Tests ships eight procedures (one-sample, Welch and paired t, Z-test, χ² goodness-of-fit, χ² independence, ANOVA, confidence interval) with a three-question wizard. Regression fits nine model families and predicts at a chosen x; Distributions returns PDF/PMF, CDF, both tails and the inverse quantile for seven families. Each panel has its own URL, from /math/stats/descriptive to /math/stats/distribution.
