Hi there,

In general, the median is determined by listing all numbers in a data set together, and then finding the one that falls exactly in the middle (or the central point).

For example, the median age of a population comprised of two 15 year olds, three 17 year olds, and two 25 year olds is 17 because, when you put all the ages in order (15, 15, 17, 17, 17, 25, 25) the value in the middle is 17 years old.

I'm including a link to the full definition below, as well as an activity that's great for a refresher course on the three types of averages: mean, median, and mode.

Hope this helps!

simple typo. the answer is 82.5.  when all numbers are put in numerical order there is no clear median.  the two middle numbers must be added and then divided by 2 to get the true median.  82.5
