Question

Consider Mary's study of whether the learning of 6th graders on a math lesson is affected by background noise level. Describe the pros and cons of Mary using a repeated measures design for this study. What would you probably choose to do?

Answer 1

Repeated measure design may be a study design wherever we have a tendency to use constant subject for each style conditions.

Step-by-step explanation:

Pros of using repeated measures design:

• All tests are performed on the same subject (students) such as IQ, age and all other similar variables, which eliminates the possibility of subject inhibition.
• The required sample size is small when different subjects can be tested on mole subjects.

Cons of using repeated measures design:

• The whole test is performed repeatedly on the same subject, this subject can have some negative effects like fatigue and loss of concentration. It affects the results.
• In our test, a variable based on the learning ability of a math lesson.
