A veterinarian wishes to compare the number of times race horses are reported to be lame during a 12‑month period, as compared with similar horses that are not raced. The veterinarian is particularly interested in whether the exercise schedule used in racing contributes to lameness, rather than the total amount of exercise. The veterinarian feels horses to be compared should be similar with regard to age, breed, and the number of weekly hours spent exercising. Which of the given study types should be used? Group of answer choices a. A matched design in which a race horse is chosen, and a horse that is the same age, the same breed, and exercised the same number of hours is chosen for comparison. b. A horse is chosen and raced for one year, but is not raced the next year. c. A group of race horses is chosen and then, from a nearby barn, a group of horses that do not race is chosen. d. None of the answer options are correct.
