Line all the numbers in order, find their average, then subtract the average from each of the numbers (If you have any negative numbers, take the minus sign off to make them positive), then add all the answers up, then divide by the number of values. Example: 100-88=12 95-88=7 90-88=2 85-88=3 80-88=8 75-88=13 12+7+2+3+8+13=45 45/6=7.5 Average=87.5=88 Average spread=7.5
88 = 75 + 13

The average of 88 and 0 is 44.

60 + 75 + 88 + 93 = 316 316/4 = 79 The average of the four numbers is 79.

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.
66, as a percentage of 88 = 100*66/88 = 75%

The average of 88 and 0 is 44.
66 is 75% of 66/(75%) = 66/(75/100) = 66*(100/75) = 88

a mean is the average of quantity, you find the sum of the quantities then divide that number by the number of quantities. For example to find the sum of 75, 88, 70, 90. Add 75+88+70+90 which equals 323 then divide by 4 and the mean would be 80.75(and possibly round the number)
