Find the median of the following sets of numbers.a 6, − 10, 8, 1, 15, 8, 3, 1, 2 b 5, − 7, 12, 7, − 3, 7, − 3, 11, 12c 12, 17, 7, 10, 2, 17, − 2, 15, 11, − 8 d − 2, − 1, − 3, 15, 13, 11, 14, 17, 1, 14

Sure, let's find the median for each set of numbers.

The median is the middle number in a sorted, ascending or descending, list of numbers. If there is an even number of observations, the median will be the average of the two middle numbers.

a) 6, − 10, 8, 1, 15, 8, 3, 1, 2

First, sort the numbers in ascending order: -10, 1, 1, 2, 3, 6, 8, 8, 15

The median is the middle number, which is 3.

b) 5, − 7, 12, 7, − 3, 7, − 3, 11, 12

Sort the numbers: -7, -3, -3, 5, 7, 7, 11, 12, 12

The median is 7.

c) 12, 17, 7, 10, 2, 17, − 2, 15, 11, − 8

Sort the numbers: -8, -2, 2, 7, 10, 11, 12, 15, 17, 17

Since there are an even number of numbers, the median is the average of the two middle numbers (10 and 11), which is 10.5.

d) − 2, − 1, − 3, 15, 13, 11, 14, 17, 1, 14

Sort the numbers: -3, -2, -1, 1, 11, 13, 14, 14, 15, 17

The median is the average of the two middle numbers (11 and 13), which is 12.
