∙ 2011-04-07 17:13:30When 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.

The mean of the data is 80.
The range is 72 minus 66 = 6
54, 56, 58, 60, 62, 64, 66, 68, 70, 72
71 is the median of those numbers.

Median is 70 The median is the middle number once you have reordered the sequence (therefore, 72 is not the median). The mode is the most common number The mean is the average.
65 is the median,
71 is the median of those numbers.
If you mean 75% of 72 then it is 54
