Thread: Correlation Co-efficient r. On a calculator

Hi,

I'm trying to find r for some problems I have. I have a casio 991ms calculator but I should be able to get by with some general instructions.

I have data similar to this

age weight
20 124
43 240
12 102
52 187

Is there a way to get these into the calculator to find r? How?

Thanks!
