Delete the 5 from the data numbers given for Example 1 and then do the following with the resulting data.

Find the median.

Data from Example 1

Given the numbers 5, 2, 6, 4, 7, 4, 7, 2, 8, 9, 4, 11, 9, 1, 3, we first arrange them in numerical order. This arrangement is

Because there are 15 numbers, the middle number is the eighth. Because the eighth number is 5, the median is 5.

If the number 11 is not included in this set of numbers and there are only 14 numbers in all, the median is that number halfway between the seventh and eighth numbers. Because the seventh is 4 and the eighth is 5, the median is 4.5.

middle number 1, 2, 2, 3, 4, 4, 4, 5, 6, 7, 7, 8, 9, 9, 11
