Mean

The mean is the average Of a group of numbers. So say you have these numbers 12, 33, 11, 45. You woul add them Up which would add up to 101 then divide by the number of numbers in the group which would be 101 divided by 4=25.25. That is your mean but if u want to round it to the nearest tenth it would be 25.3
