First, put the numbers in numerical order from 4-13. 4,5,5,6,10,11,12,13 Then, the number that is in the middle will be the answer, which is 6 and 10. Then, you need to find the mean of these two numbers. To find the mean, add 6 and 10, then divide by two. The answer is then 8.
To find the median, you first need to put all the numbers in order like this:
4,5,5,6,10,11,12,13
Then you need to count up how many numbers there are. There are 8 numbers total here. Since this is an even number there is going to be two medians. So find the middle and the answer will be... median= 6 and 10
