You can put this solution on YOUR website! First sort the numbers into ascending order (from least to greatest):
68,69,71,75,76,76,81,82,86,88,93,94,95,95,96
To find the mean, add up all of the numbers and divide the sum by the number of numbers (which in this case is 15).
So the mean is 83
To find the median, count off about 7 spaces(it's close to half of the size of the list) until you hit the middle number. Now count count off about 7 spaces from the end of the list until you hit the middle.
68, 69, 71, 75, 76, 76, 81, , 86, 88, 93, 94, 95, 95, 96
Median=82
So the median is 82
