Scientists interested in the effect of exercise on the duration of sleep conducted the following study: 180 overweight men were randomly assigned to two groups. One group was instructed to perform aerobic exercise for about an hour per day, and the other group was instructed to continue with their exercise-less routine. The sleep duration of each subject was measured at two points: before the randomization and 101010 weeks after it.

What type of statistical study did scientists use?
