A consultant stops by your office and pitches a new, computer-based ethics training program that she claims will provide superior results to your department's current face-to-face ethics training program as evidenced by final exam scores. The chief is concerned that officers' prior experience and training may skew the results, and instructs you to evaluate the new program controlling for officers' experience. To deal with these concerns, you decide to match pairs of officers based on their years of experience in law enforcement. One member of each pair undergoes the standard training, and the other member of the pair takes the new course. Which of the following would be the most appropriate significance test of an observed difference between the means of the two groups?
