When they ask for the 'mean' they are really asking for the average of all those numbers.

All you have to do is add those up: 76+54+92+88+76+88+75+93+92+68+88+76+76+88+80+70+88+72= 1440

And then divide by how many numbers we added up. In this case, we added up 18 different numbers. So:

1440 / 18 = 80

80 is your 'mean' or average number.
