Apply quick select to find the median of the list of numbers 9, 12, 5, 17, 20, 30, 8.

Solution:

A median is a value which separates the higher numbers from the lower numbers in the data sample.

It actually represents the middle value of the data sample.

To find the value of the median, we have to place the numbers in order of value and find the middle point.

If two sets of numbers are present, we have to find the middle point by adding them and dividing by 2.

The given list of numbers is

9, 12, 5, 17, 20, 30, 8

By arranging it

5, 8, 9, 12, 17, 20, 30

Here the middle term is 12.

Therefore, the median is 12.
