The study conducted by Dr. Campbell as described is an experimental design, because the researcher controls the variables and measures the results.
<h3>What is an experimental study?</h3>
In an experimental study, the researcher usually divides participants into two groups. One of those groups will be exposed to a new variable. The group that will not be exposed to it is called control group. Then, the results obtained from both groups are compared to see if the variable had any influence over them.
That is precisely what Dr. Campbell is doing, which means he is conducting an experimental design study. His control group uses traditional methods, while the other group is exposed, so to speak, to a new study method. Then, the results of their final exams are compared.
With the information above in mind, we can conclude that Dr. Campbell is conducting an experimental design study.
