Just download the manual for Texas BA II Plus. It shows you the steps. You have to put the calculator in linear regression mode. Then enter your data, and the calculator gives you the correlation coefficient (this is the "r" value under the "STAT" sheet).
Once you have "r" you can plug-n-chug the covariance formula (see jun2009's post above). |
