Now look at the data you have collected on your chart. Put a star by the most expensive football. Put a star by the least expensive football.
Now, write the prices of the footballs from least expensive to most expensive on your paper.
Circle the price that is in the middle. The number you circled is the median number, or price of this group of footballs.
Let's see how this would look on a graph arranged from least expensive to most expensive footballs.
