5,15,13,15,5,10,7,20,25,15. What is the median?

First arrange them in order from the smallest to the largest

5,5,7,10,13,15,15,15,20.25

then the median will be 13 and 15

add them together then divide it by 2

13+15=28

28/2=14

Set them in order then start canceling out from both sides until you reach the middle ... so you'll have it like this: 5,5,7,10,13, 15,15 15,20, 25

then you cancel out 25 with 5 then 20 with the second 5 and so on until you end up with 13 and 15 in the middle with means you'll have to get their average since you can't cancel them out. doing this you'll end up with 13+15/2 = 14 and that's your answer!
