Reil [10]

Answer:

First, let's add the missing piece of information

A school psychologist wants to test the effectiveness of a new method of teaching FrenchFrench. She recruits 100100 firstfirst​-grade students and randomly divides them into two groups. Group 1 is taught by means of the new​ method, while group 2 is taught by traditional methods. The same teacher is assigned to teach both groups. At the end of the​ year, an achievement test​ (graded on a scale from​ 1-10) is administered and the results of the two groups are compared.

The CORRECT ANSWER IS A.

A. Group 2 serves as the control group because this group corresponds to the standard method that will be compared to the other method.

Explanation:

A control group

The control group acts as a baseline treatment that is employed in contrasting it to the other form(s) of treatments.

Ex: In this case study, a school psychologist wants to test the effectiveness of a new method of teaching French, to see if the ones taught by using a new method (are placed in group 1) do better in learning French than those taught with the traditional method (are placed in group 2). The students being taught French with the traditional method (group 2) would serve as the control group (as this is the present, proven and acceptable practice of teaching French. The factor is the method of teaching French. There are two treatments: new method and traditional method.

Therefore, the option A. is THE CORRECT ANSWER

A. Group 2 serves as the control group because this group corresponds to the standard method that will be compared to the other method.
