Another way to calculate the correlation coefficient (r) is to multiply the slope of the regression line by the standard deviation of X and then divide by the standard deviation of Y. Covariance: a measure of how much two variables change with respect to one another.

The formula for a combination is: nCr = (n!)/(r!( to access the probability menu where you will find the permutations and combinations commands. Using the TI-84 Plus, you must enter n, insert the command, and then enter r. See the PROB menu in the first screen. See the shortcut menu in the second screen.

Find the product of the z-scores by multiplying each of the pairs of z-scores (zxzy). Then sum the products (S zxzy). Finally, divide the sum of the products by the number of scores (n) to find the correlation coefficient, r. Recall that z scores have a mean of zero.

=CORREL(A2:A11,B2:B11) A correlation coefficient of 0.998829 means there's a strong positive correlation between the two sets. As the 'X Variables' increase, the 'Y Variables' increases also.

Divide the sum by sx ∗ sy. Divide the result by n – 1, where n is the number of (x, y) pairs. (It's the same as multiplying by 1 over n – 1.) This gives you the correlation, r.
