Answer
There is no real value of counting the mean.
Work Step by Step
The mean can be counted by summing all the data and dividing it by the number of data: $\frac{10+29+26+...+23}{33}=15.03$. The median is the average of the 1 or 2 (here 1) middle data:(16)/1=16. There is no real value of counting the mean.
