Hello,

Wasn't quite sure where to post this, so I apologize in advance if it's in the wrong section.

I have borrowed a T1-83 plus calculator from a friend that has no instruction manual. I am trying to figure out how to use it to find:

A) Sample covariance
B)Correlation coefficient

Any help would be greatly appreciated!

You can download a guide book from
http://education.ti.com/educationportal/sites/US/productDetail/us_ti83p.html

The site also has tutorials and lots of other stuff for the TI-83
