Question

A) Two different methods of teaching number division in two respective samples of elementary school students were compared using a test of division ability, which was administered at the end of the study. In addition, the children were also measured at the beginning of the study on an intelligence test yielding an intelligence score. You want to know if there are differences between the two methods using the data that you have collected.

B) I have tested some students in a traditional high school and others at an alternative high school. I collected data using the same test, both at the beginning and at the end of the semester. You want to compare the performance of the two schools based on the data you have collected.

Answer 2

A) One between-subjects variable and one within-subjects variable repeated measures design. This is because there are two different methods of teaching number division, which represents the between-subjects variable, and the test of division ability is administered at the end of the study, representing the within-subjects variable.

B) One between-subjects variable and one within-subjects variable repeated measures design. This is because there are two different schools - traditional high school and alternative high school, which represents the between-subjects variable, and the test is administered both at the beginning and at the end of the semester, representing the within-subjects variable.
