Problem-Solving and Data Analysis practice question

Answer: A. 7

The median is the middle value of an ordered list. With five values, the 3rd one is the middle: 4, 7, [7], 9, 13 → 7. Choice B is the mean; don't confuse the two.

Why the other answers are wrong

B. 8

8 is the mean (40 ÷ 5), not the median. The median is the middle value of the ordered list, which is the 3rd of five numbers.

C. 9

9 is the 4th value in the list; with five numbers the middle position is the 3rd, which is 7.

D. 40

40 is the sum of all five values — that's the first step toward the mean, not the median.
