Rejecting and Failing to Reject the Null Hypothesis

Rejecting and Failing to Reject the Null Hypothesis Rejecting and Failing to Reject the Null Hypothesis Just because two or more values are different does not mean that they are different in a statistically significant manner. Researchers rely on the p values that are generated for each of their statistical tests to determine significance. If the p value is larger than the alpha, then they are not different in a statistically significant manner, and therefore the values are not considered different. In this journal activity, consider these concepts in terms of the differences between null and alternative hypotheses.
