The prompt

Help me choose the right statistical test for my data and explain the result in plain words. My question: [e.g. did the new page design increase sign-ups? Do men and women rate the product differently?] My data: [describe variables, types (numbers, categories), sample sizes, how it was collected] Sample of the data (optional): [paste a few rows] Do this: 1. Restate my question as a null and alternative hypothesis in simple terms. 2. Recommend a test, with one line on why it fits (and one alternative if assumptions fail). 3. List the assumptions and how to check each one. 4. Show how to run it in [Excel / Google Sheets / Python / R], with code or formulas. 5. Once I paste the output, explain the p-value, effect size and confidence interval in plain words, and what I can and can't conclude. Warn me about common mistakes: tiny samples, testing many things at once, confusing correlation with causation.
