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
