Question

What is the median of the numbers 21, 23, 76, 47, 55, 135, 45, 30, 17?

Answer 1

The median is 45.

Explanation:

Let's put all of the numbers in numerical order first:

`17, 21, 23, 30, 45, 47, 55, 76, 135`

From here, we cross off the lowest and highest numbers in our data set. We repeat the process until we get to our number.

`21, 23, 30, 45, 47, 55, 76`

`23, 30, 45, 47, 55`

`30, 45, 47`

`45`

Median=`45`
