We need to calculate the mean for each of them and then find the standard deviation and then figure out our coefficient of variation.
00:16
We can use our calculator for most of this.
00:20
So the coefficient of variation, we take our standard deviation and divide it by the mean.
00:27
Mean is just the average.
00:29
So if you wanted to find the average by hand, you could.
00:32
But on your calculator, you're going to hit the stat button and then hit enter on edit.
00:39
And in list one, you are going to enter in each of these separately.
00:43
So you're going to have to do height first, get your answers, and then do weight.
00:48
So enter in all of your height values.
00:51
And you're going to hit stat and go over to calculate...
