Mean or Arithmetic Mean or Average - The sum of all of the numbers in a list divided by the number of items in that list.

The mode is the number that is repeated more often than any other, so 13 is the mode. The largest value in the list is 21, and the smallest is 13, so the range is 21 - 13 = 8.

{(n + 1)/2}th value, where n is the number of values in a set of data. In order to calculate the median, the data must first be ranked (sorted in ascending order). The median is the number in the middle. Median = the middle value of a set of ordered data.

is/of = %/100 or part/whole = %/100
