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.

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.

Participants in both types of experiments are all measured the same number of times.

The researcher must compute a pooled variance to compute a t statistic.

The researcher must compute an estimated standard error for the mean difference score to compute a t statistic.

A matched-subjects experiment produced a t statistic with a df of 9. How many subjects participated in this study?

For a repeated-measures experiment comparing two treatment conditions, the t statistic has a df of 11. How many subjects participated in this study?
