Lee took a survey for the school newspaper and received the following data about the number of hours classmates studied per week: (1,2,4,5,6,8,9,10,10). Express as a common fraction the positive difference between tthe median and mean of this set of data.

To find the mean, add the numbers and divide by 9.
To find the median, find the number in the middle. 
Find the mean (average)
1 + 2 + 4 + 5 + 6 + 8 + 9 + 10 + 10 = sum
Average = sum/9
The median is the middle value, 6
mean  median = postive difference
Then express this difference as a fraction
