Could you please tell me how to do this? I’ve been reading my manual but recently lost it Any help would be much appreciated. Thanks!

Never mind, I found it on another thread. Gotta love AF!

can you put the link here. Thanks S

thanks.

Use the stat WS to calculate the r, sigma X and sigma Y. Take the product and you have the Covariance!

Just a clarification- in the covariance forumla- dow e use n or n-1 in the denominator? I assume s in BA II uses n-1 and sigma uses n. Can somebody confirm? S
