Use grid paper to find the median of the data.
9,7,2,4,3,5,9,6,8,0,3,8
The median is

You want to put the numbers in order from least to greatest like this-
0,2,3,3,4,5,6,7,8,8,9,9
then you want to start from the left end and the right end then you start crossing them off until you have a median, you keep crossing off until you get 5 and 6 in the middle, now you have to find the mean of the two numbers you add them together than you divide by 2 like this- 5+6=11 11/2=5.5
5.5 is your answer
