Identify which of the followings are advantages and not an advantages?

a. In the repeated-measures t test the participants in one treatment are not substantially different from the participants in another.
b. The repeated-measures t test can handle more than two conditions.
c. The repeated-measures t test uses half the number of participants.
d. The repeated-measures t test can handle categorical data.

The advantages are:

a. In the repeated-measures t test the participants in one treatment are not substantially different from the participants in another.

c. The repeated-measures t test uses half the number of participants.

Not Advantages are:

b. The repeated-measures t test can handle more than two conditions.

d. The repeated-measures t test can handle categorical data.

Step-by-step explanation:

In repeated-measures t test you do not need a large sample size instead the same group of participants are exposed to two different treatments. Because each participant is taking part in all treatments, need at least half the amount of participants. This saves on collecting large amounts of data to analyse.

Therefore option a. In the repeated-measures t test the participants in one treatment are not substantially different from the participants in another and option c. The repeated-measures t test uses half the number of participants. are the advantages while options b and d are not advantages.
