Design an Experiment to Study the Relationship Between Class Attendance

Question

Examlex · Accepted Answer

The Answer is To study the relationship between class attendance and exam grades, an experiment can be designed where students are randomly assigned to two groups: one group is required to attend all classes, while the other group is not required to attend any classes. Both groups would take the same exams and their grades would be compared at the end of the semester.

The most appropriate method for studying this relationship is a randomized controlled trial (RCT). RCTs are considered the gold standard for determining cause-and-effect relationships because they involve randomly assigning participants to different groups, which helps to minimize bias and confounding variables. In this case, by randomly assigning students to the attendance and non-attendance groups, we can be more confident that any differences in exam grades are due to the attendance policy and not other factors.

Additionally, using an RCT allows for the establishment of a clear control group, which is essential for comparing the effects of class attendance on exam grades. This method also allows for the collection of quantitative data, which can be analyzed using statistical methods to determine the strength and direction of the relationship between class attendance and exam grades.

Overall, a randomized controlled trial is the most appropriate method for studying the relationship between class attendance and exam grades because it provides a rigorous and systematic approach to determining causality and minimizing potential biases.
