Answer:
what are you supposed to be doing
 
        
                    
             
        
        
        
In order to find the median the 1st thing I would do is put the number in order
80,84,87,88,88,90,90,95,98,100 
then cross them out Start with left then go the right and so on...
until you get 1 number in the middle left (Since theirs 2 numbers in the middle add them up and divide by two ) 88+90=178   178/2=89
Median = 89 
Now in Order to find the mean add up all the numbers and divide by however many numbers their are 
You should get 900 then divide by 10 because their were 10 numbers 
So Median=89 &  Mean=90
