A medicаl dоctоr rаndоmly selects 80 pаtients from her clinic. She gathers data from their records about how many times per week they exercise and how many servings of fruits and vegetables they eat per day. The doctor then identifies two groups: the group of patients who exercise 0 or 1 days per week and the group that exercises 2 or more days per week. Then, the doctor compares the total number of servings of fruits and vegetables per day eaten by each group. What type of study is this (experimental or observational), and why?
