Hypothesis tests and p-values
A coin lands heads 60 times out of 100. Is it rigged, or just lucky? Hypothesis testing answers "could chance alone explain this?" You'll simulate thousands of fair coins to compute a p-value by hand, find the line between "surprising" and "not", and learn how A/B tests work and how p-hacking fools people.
