The criterion an experimenter uses to decide whether to accept or reject the null hypothesis is the significance level, also known as alpha. The significance level represents the maximum probability of rejecting the null hypothesis when it is actually true. Commonly chosen values for alpha are 0.05 and 0.01, indicating that the experimenter is willing to accept a 5% or 1% chance of incorrectly rejecting the null hypothesis. If the p-value calculated from the data is less than the significance level, the null hypothesis is rejected as unlikely to be true.
