Answer by Earlsdon(6294) (Show Source):
You can put this solution on YOUR website! Remember that the median of a set of numbers is the middle number of the set.
In this case, you have 16 numbers so there is no middle number, so you take the two middle numbers and find their average (mean) and that will be the median.
So what you need to do is write down all of the numbers given in the stem-and-leaf plot, from least to greatest, (make sure that you copy all 16 of the numbers) then find middle two, add them together and divide by 2, and this will give you the median.
Good luck!
