The distribution of differences between means is essentially the same concept as the distribution of difference scores. (True or False)

Question

Quizplus · Accepted Answer

The distribution of differences between means typically refers to the distribution resulting from the difference between the means of two or more groups, often used in hypothesis testing to determine if there are significant differences between groups. The distribution of difference scores, however, usually refers to the distribution resulting from subtracting one set of scores from another set of scores within the same group or individual, often used in paired samples or repeated measures designs. These concepts, while related in that they both involve differences, are used in different statistical contexts and analyses.
