WebMar 25, 2024 · A binomial test compares a sample proportion to a hypothesized proportion. For example, suppose we have a 6-sided die. If we roll it 24 times, we would expect the number “3” to show up 1/6 of the time, e.g. 24 * (1/6) = 4 times. If the number “3” actually shows up 6 times, is that evidence that the die is biased towards the number “3”?
