PLEASE HELP! Find the median of the stem and leaf plot

Answer: 20
Step-by-step explanation:
Median means number in the middle
eliminate largest then smallest then next largest then next smallest etc...
do that until you get one finale number. Doing that to this leaf plot will end up with 19 and 21. If you have two numbers you add both of them and divide by 2. doing that will give you the number in between those two numbers or 20 in this case.
