An instructor wants to find out if administering essay exams improves student learning. In one class, the instructor continues using the usual testing method, while in another class, essay exams are given. The instructor then compares the learning outcomes between the two classes. Which group is the one receiving the essay exams?
Explanation
The experimental group is the one that receives the treatment or intervention—in this case, the essay exams—while the control group does not. This setup allows the instructor to observe any differences caused by the new testing method.
