Suppose that Mary, Gary, and Larry have been asked to randomly sample 100 patients' visit records from a file of 2000 patient records and record the amount of time the attending physician spent with each patient. Gary suggests the time of year during which the patient was seen may be a confounding variable and strongly advises dividing the year into quarters (Jan - Mar, Apr-Jun, Jul-Sep, Oct- Dec) and randomly selecting 25 patient records from each quarter. Which of the following best describes Gary's sampling plan? (A) A simple random sample (B) A systematic random sample (C) A stratified random sample (D) A cluster sample (E) A convenience sample
