Question

Thirty students participated in a study designed to evaluate a new online homework system. None of the students had used an online homework system in the past. After using the system for a month, they were asked to rate their satisfaction with the system using a five-point scale. (a) What are the experimental units, the treatment, and the outcome for this experiment? Can we use the term subjects for the experimental units? Explain your answers. b) Is this a comparative experiment? If your answer is Yes, explain why. If your answer is No, describe how you would change the design so that it would be a comparative experiment. c) Suggest some different outcomes that you think would be appropriate for this experiment.

Explanation / Answer

a.)   Experimental units - Thirty students who participated in the study.

Treatment - study designed to evaluate online homework system.

Outcome - To study the satisfaction of students for online homework system.

b.) No, this is not a comparative experiment.

Comparative experiment is an experiment that compares the effect of two treatments. So in order to make this design a comparative experiment, we may use one more homework other than the online system and compare the rate of satisfaction of students towards the two treatments.
