What is the median of the data in this stem-and-leaf plot?

It would be 23.

To get the median, first you would have to list all of the numbers from the stem-and-leaf plot in order:

14, 15, 17 ,21 ,22 ,24 ,24 ,26 ,30 ,32
Then you have to find the number in the middle. 

22 and 24 are in the middle.

However, we can't have 2 numbers as the median!
We would add both of the numbers then divide by 2, or you could use the number that is between 22 and 24.

22 + 24= 46
46/2 = 
23

The answer would then be 23

(*To tell whether the median is 2 numbers, check and count the set of numbers and see whether if the result is an even or odd number. Odd number have 1, while evens has 2.)
