Median of 3, 9, 4, 7, 5

Step by step

The question

Question: find the median of 3, 9, 4, 7 and 5.

The median is the middle number, once the numbers are in order.

1 Put them in order

First we put them in order, smallest first: 3, 4, 5, 7 and 9.

We still have 5 numbers.

None is lost.

2 Find the middle

We cross out the smallest and the biggest, one pair at a time.

And the next pair.

5 is left in the middle.

So the median is 5.

Let's look back.

First: put them in order.

Last: find the middle.
