    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!
