median of {5, 15, 9, 13} is 11 To find the median of a dataset sort the data into order and the median is the middle one; if there are an even number of items in the dataset, then the median is the mean average of the middle two. {5, 15, 9, 13} → {5, 9, 13, 15} There are 4 data items, → median is mean of {9, 13} = (9 + 13) / 2 = 11.
11/15= 11 ÷ 15= 0.73313/20= 13 ÷ 20= 0.65therefore 11/15 is bigger than 13/20.
