The significance level, denoted by alpha (α), represents the probability of rejecting the null hypothesis when it is actually true. Commonly used significance levels are 0.05 and 0.01. The critical value is then found using a statistical table or software, such as a t-table or a z-table, based on the chosen significance level and the degrees of freedom for the test.
