Computing Covariance with BII Plus Pro

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 word


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
