Full teaching script
- Today: Hypothesis testing. Our goal: Run and interpret a significance test.
- Take one idea at a time. Pause after each sentence; ask for repetition whenever you need it.
- You never prove a claim; you test how surprising your data would be if nothing were happening. That 'nothing happening' is the null hypothesis. You compute a test statistic, then a p-value: the probability of data at least this extreme under the null. Below your chosen significance level (often 5%) you reject the null. p is not the probability the null is true, and 'not significant' is not proof of no effect — it may just be a small sample. Always report effect size and confidence interval alongside it.
- Together: choose one example from the explanation and show how it works. What do you notice?
- Your turn: Test whether a coin flipped 100 times giving 61 heads is fair, at 5%.
- Reflect: what made sense, and what would you like explained differently?
