In an experiment, we are interested in whether the time of day (morning or evening) impacts an individual's ability to catch a baseball. For the experiment, 30 baseballs are thrown to the individual, and the total number caught is recorded. Suppose we are specifically interested in if there are more catches in the morning than in the evening. 19. Would this experiment be best set up as a paired design, or an independent design?
