In this problem, we are calculating the correlation coefficient.
00:05
So just a reminder, the correlation coefficient is our r value.
00:09
So if you get the r squared value, you want to take the square root to find the correlation coefficient.
00:18
Now, some calculators will just give you the correlation coefficient, but some of them will give you the r squared, which is the coefficient of determination, which is a little bit different.
00:27
But you can find the correlation coefficient by taking the square root.
00:31
And then matching it to the sign of the slope of our linear regression model.

So in this case, what i did was i used a graphing calculator, and under l1, i typed in all of my heights, 77, 76, and so on, down to kyle orton at 76...
