Compare Means

Compare a numeric variable across groups (t-test / ANOVA / non-parametric) + post-hoc.

Overview

Tests whether a numeric variable (e.g. citations) differs across the levels of a grouping variable: group descriptives, the appropriate omnibus test (t-test / one-way ANOVA, or non-parametric Mann-Whitney/Kruskal-Wallis) and pairwise post-hoc comparisons. Can also compare across several binary group columns at once.

Inputs

Outputs

Descriptives (Table) — per-group descriptive statistics.
Tests (Table) — omnibus test results.
Post-hoc (Table) — pairwise comparisons.

Controls

Dependent (numeric) — the variable compared.
Group by — the grouping variable (or use multiple binary group columns).
Alpha — significance level.

Actions: Compare.
