The 'Mean' (Average) is 18.75. (Often rounded to 19) The Median is the 'middle value' in your list. When the totals of the list are odd, the median is the middle entry in the list after sorting the list into increasing order.
In math, median is used to refer to the middle number in a group. To determine the median, you order the numbers from (lowest) to (highest) and find the middle number in the series. If there are two middle numbers, then add them together and divide by two to find the mean.
