Researchers designed an experiment to investigate the effects of background auditory distraction on reading comprehension. They recruited a sample of 25 undergraduate students to complete two computer-based reading comprehension tests under different environments:
The time taken (in seconds) to complete each comprehension test was measured. The order of the conditions was counterbalanced to minimize order effects.
Explain why the researchers chose to use a repeated measures design in this study.
