Suppose that you conduct a study that compares the pretest anxiety scores with the posttest anxiety scores of the clients in your support group. You find that posttest scores are better than pretest scores but the difference between these two sets of scores is not statistically significant. Explain why you should not conclude that your support service was found to be effective.
What will be an ideal response?
Ans: Varies. In order to conclude that your service was found to be effective, you must have two pieces of information: the data must be in the direction that shows success and the data must be statistically significant. If the data are not statistically significant, you have found chance, which cannot be relied upon to give you the long-term truth.
