Statistical Hypothesis Testing

This one gives Claude the framework to run proper statistical hypothesis tests when you're analyzing data. It covers the standard stuff: t-tests, chi-square, ANOVA, and correlation tests, plus the conceptual bits like null hypotheses, p-values, and significance levels. Useful when you need to know if your A/B test results actually mean something or you're just looking at noise. The repo has 245 stars and passed security audits from three different services, so it's been vetted. It's part of a larger collection of AI prompts, so you're getting a focused subset rather than a standalone tool. Solid if you're doing any kind of statistical analysis and want Claude to handle the mechanics correctly.
