Dr. Grant is conducting research on stress management. Group A received progressive relaxation training prior to test taking, while Group B received no training. Group A is the, while Group B is the
a. treatment group/placebo group
b. experimental group/control group
c. control group/treatment group
d. placebo group/control group
The Correct Answer and Explanation is:
The correct answer is:
b. experimental group/control group
Explanation:
In the context of research studies, the terms experimental group and control group are commonly used to refer to the two types of groups involved in testing the effects of a particular intervention or treatment.
- Experimental Group: This group receives the treatment or intervention being tested. In this case, Group A received progressive relaxation training prior to test-taking, which is the intervention Dr. Grant is researching. Therefore, Group A is the experimental group, as it is subjected to the treatment (relaxation training) to observe how it impacts stress management before a test.
- Control Group: The control group, on the other hand, does not receive the experimental treatment. This group is used to compare the effects of the intervention on the experimental group. In this study, Group B received no training, making it the control group. By comparing the results from the experimental group (Group A) to the control group (Group B), Dr. Grant can determine whether the progressive relaxation training has a significant effect on stress management and test-taking performance.
The control group serves as a baseline, helping researchers understand whether the observed effects in the experimental group are actually due to the intervention or just a result of other factors. Without a control group, it would be difficult to make a fair comparison and determine the true effectiveness of the treatment being tested.
To summarize, Group A is the experimental group because they received the progressive relaxation training, while Group B is the control group because they received no intervention, which allows for comparison to understand the effect of the relaxation training.
