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?

a. The researcher computes difference scores to compute a t statistic.
b. 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.
c. The researcher must compute an estimated standard error for the mean difference score to compute a t statistic.
d. Participants in both types of experiments are all measured the same number of times.

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

Step-by-step explanation:

As already defined that 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.

Both repeated-measures experiment and a matched-subjects experiment when used to compare two treatment conditions use the same t statistic. Therefore, researcher must compute an estimated standard error for the mean difference score to compute a t statistic.

a) 32pie square meters

step-by-step explanation:

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
