For the data 11, 15, 13, 12, 10, 8, 11, 7, 15, 11, 13, 7, 11, which of the following is true?

Solution

Correct Option: 3

Sum = 144, count = 13, so Mean =144/1311.08= 144/13 \approx 11.08.

Sorted: 7,7,8,10,11,11,11,11,12,13,13,15,15. Median (7th value) = 11.

Mode = 11 (appears 4 times).

So Mean > Mode = Median.
