Repeated-measures experiments measure the same set of research participants two or more times, while matched-subjects experiments study participants who are matched on one or more characteristics. Which of the following are true for both a repeated-measures experiment and a matched-subjects experiment when used to compare two treatment conditions? Check all that apply. Participants in both types of experiments are all measured the same number of times. They both use the same t statistic. The researcher computes difference scores to compute a t statistic. If the researcher has n number of participants to use in the experiment, then the degrees of freedom will be the same in a repeated-measures experiment or in a matched-subjects experiment. For a repeated-measures experiment comparing two treatment conditions, the t statistic has a df of 31. How many subjects participated in this study? 64 31 62 32 A matched-subjects experiment produced a t statistic with a df of 13. How many subjects participated in this study? 13 14 26 28
