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”?

A random binomial process is repeated several times, in an attempt to see if the process is fair - i.e., the actual probability of the event occurring matches the expected probability. In order to test if the process is fair, first determine if the conditions required for the normal approximation to the binomial are met. " - Binomial hypothesis
