To see how tall your son is compared to other children his age, you could use a different type of average called the median: that's the middle number in a data set.
To find the median:
- Order the numbers from least to greatest.
- Find the middle number.
For example, look at this number set: 6, 2, 10, 5, 7
Now order the numbers from least to greatest: 2, 5, 6, 7, 10
Pick out the middle number: 2, 5, 6, 7, 10
6 is the median, or middle number. In this set, half the numbers are less than 6 and half the numbers are greater than 6.
