Find the median
Key: 2|8=28 years
To find the median, we need to first arrange the numbers in order:
1, 2, 2, 4, 4, 8, 9
There are 7 numbers in total, so the median would be the middle number when arranged in order. In this case, the median is the 4th number which is 4.
Therefore, the median age is 4 years.
