So the first thing when doing this, you have to find the average of your x value and then you have to find the average of your y value.
00:40
Then you have to find the difference between each one of your x values and your mean of x.
00:50
Then you have to find your difference between each one of your y value and the mean of y.
00:56
Then you have to multiply your x minus your mean of x times your y minus your mean of y.
01:10
Then you have to total that up.
01:15
Then you have to take x minus the mean of x and you have to square it...
