What is the sum of the mean, median and all modes of the following set of data? Express your answer as a mixed number. 
Mean: ( 0+0+1+2+16+23+15+2+1 )/ 9
60/9
6 2/3
Median: 0, 0, 1, 1, 2, 2, 15, 16, 23
The middle number is 2 because when we cross out from the outside the last number we are left with, ( the middle ) is 2.
Mode(s): Out of the data set of 0, 0, 1, 1, 2, 2, 15, 16, 23, we see that the most frequently appearing numbers are 0, 1, and 2.
6 2/3 + 2 + 0 + 1 + 2 = 11 2/3
