repeated measures and matched subject experiments 12.04 Engagement Problems: The t Test for Two Related Samples Graded Assignment Due Thursday 06.21.18 at 11:00 PM Average: 13 3. Repeated-measures and matched-subjec ts experiments 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 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 The researcher must compute an estimated standard error for the mean oifference score to compute They both use the same t statistic. The researcher computes difference scores to compute a t statistic ? The researcher must compute a pooled variance to compute a t statistic For a repeated-measures experiment comparing two treatment condtions, the t statistic has a of of 15. How many subjects participated in this study O 16 0 30 0 15 0 32 A matched-subjects experiment produced a t statistic with a f of 14. How many suibijects participated in this study 0 28 0 15 0 30 ??? 3 5 6 8 0 W EExplanation / Answer
a) For both repated measures and matched pair, researcher must calculate estimates of standard error of mean difference score and must use same t-statistic and computes difference scores for t-statistics.
b) if a repeated measure exp has df = n, then number of participants are n+1. Thus, there are 16 participants in the experiment.
c) Similarly, for matched subjects expreiments, the number. of participant are 14+1 = 15.
