An experimenter wanted to test the hypothesis that women who eat large meals are not liked as well as women who eat smaller quantities of food by using the one factor repeated measures design. Participants in the study watched a videotape of a woman eating a small nutritious snack, a normal meal, or a huge meal while talking to another person. Each participant viewed three different versions of
the videotape, each with a different woman (Pat, Sue, and Deb) eating a different amount of food. After viewing the videotape, participants filled out a questionnaire about how much they liked each of the women they had seen in the videos. If the three women who appear in the video all appear to be about the same weight, a good way to ensure that their weights are the same would be to have _____.
a. high internal validity in the experiment
b. all treatment conditions counterbalanced for weight of stimulus women
c. high external validity in the experiment
d. high inter-rater agreement among people who rated the women's weights
D
If the people who estimate the weights of the three stimulus women agree to a great extent, then the experimenter can be confident that the participants will regard them the same way.
