Interpret charts to find median

Some students compared how many blocks they live from school.

 Name Number of blocks Peter 4 Rogert 5 Martha 7 Lucas 9 Sam 4 Anna 9 Andy 5

What is the median of the numbers?

When the numbers are arranged from least to greatest, the median is the number in the middle.

Read the numbers off of the table.

 4 5 7 9 4 9 5

First, arrange the numbers from least to greatest:

 4 4 5 5 7 9 9

Now find the number in the middle.

 4 4 5 5 7 9 9

The number in the middle is 5. The median is 5.
