For the data set 40, 60, 64, 64, 72, what is the MEDIAN? (Note its relationship to the mean.)
Show answer and explanation
Correct answer: A. 64
- A. Correct. With values ordered (40, 60, 64, 64, 72), the middle (3rd of 5) value is 64. (The mean here is (40+60+64+64+72)/5 = 60, illustrating how median and mean can differ in a skewed set.)
- B. 60 is the MEAN of this set, not the median.
- C. 62 is neither the median nor the mean here.
- D. 68 is not the middle value of the ordered set.
