A school psychologist wants to test the effectiveness of a new method of teaching art. She recnuits 700 sixth-grade students and randomly divides them into two groups. Group 1 is taught by means of the new method, while grouD 2 is taught by traditional methods. The same teacher is assigned to teach both groups. At the end of the year, an achievement test is administered and the results of the two groups are compared. Complete parts (a) through (h) below. (a) What is the response variable in this experiment? O A. The score of group 2 on the achievement test O B. The scores on the achievement tests of both group 1 and group 2 O C. The score of group 1 on the achievement test O D. The students' ability in art (b) Is the response variable qualitative or quantitative? O A. The response variable is qualitative because it is a characteristic. O B.
