The level of significance (α) is the probability that the test statistic will fall into the critical region when the null hypothesis is true. This level is set by the researcher. The conclusion is the final decision of the hypothesis test.

The critical value is a number based on the type of test (one tailed vs. two tailed), degrees of freedom, and alpha level. The critical value gives information regarding how probable a result would be,…
