Day 35 · Significance 47 min 40 XP
⚖️Hypothesis testing and p-values
Is that difference real or just luck of the draw? A hypothesis test gives a disciplined answer, but p-values are widely misread, so today is as much about their limits as their use.
What you'll learn
- State a null and alternative hypothesis
- Run T.TEST in Sheets and read the p-value correctly
- Name three things a p-value cannot tell you
