Given the set of numbers:
22, 24, 20, 18, 14, 16, 23 and 12
Let's find the median.
The median of a set of numbers is the middle number when the numbers are arranged from the least to the greatest.
Arrange the numbers from the least to greatest, we have:
12, 14, 16, 18, 20, 22, 23, 24
The middle numbers are:
18 and 20
Since we have two middle numbers, the median will be the average of the two middle numbers:
[tex]\frac{18+20}{2}=\frac{38}{2}=19[/tex]Therefore, the median of the sizes of shirts is 19.
