Individual skill

hypothesis-testing

Walks through hypothesis testing for a specific business question. Defines null and alternative hypotheses, selects the specific test (t-test, chi-square, ANOVA, Mann-Whitney), specifies the decision rule, and interprets the result in plain language. Use when the user wants to determine if a difference, trend, or relationship in their data is statistically meaningful or likely due to chance. Do NOT use for exploratory data profiling (use eda-framework), correlation without causation testing (use correlation-analysis), or building predictive models (use regression-guide).
