To find the median we put the number in order:
3, 3, 5, 7, 8, 9, 11
So, 3 on the left, and 3 on the right and we get the median in the middle.
So, for the median the answer is 7.
To find the mode we have to see the number that appears the most:
3, 3, 5, 7, 8, 9, 11
So, for the mode the repeating number is 3.
To find the range we have to subtract the highest and the lowest:
11 - 3 = 8
So, for the range the answer is 8.
