The median is the middle value in a distribution. The number of values is the sum:
5 + 6 + 5 + 8 + 6 + 1 = 31 values.
Consider the 31 values arranged as follows:
20, 20, 20, 20, 20, 21, 21, 21, 21, 21, 21, 22, 22, 22, 22, 22, ...............24, 26
For a set of n numbers, the median is that ranked$$\frac{1}{2}(n+1)=\frac{1}{2}(31+1)=16$$
So the median in this case is the 16th value from the left in the ordered arrangement above. Can you find it?
