well, the numbers are 5,7,11,13

I'm sure you can figure the mean and median.

Mean=9
Median=11
Is it right?
Then the difference between them is -2.
But here in the answer sheet the ans is 0!!im really confused
Answered by Steve
since there is an even number of values, the median is the average of the two center values: 9, not 11
