What is the range of the test scores: 24, 38, 19, 45, 52, 31, and 28?
Answer and explanation
Correct answer: C. 33
- Step 1: Range is defined as the difference between the maximum and minimum values. Step 2. Maximum score = 52, minimum score = 19. Range = 52 - 19 = 33. Answer: 33. Why not the others: 28 is the median; 31 is near the mean; 35 subtracts from a wrong minimum.
