Question

In the equation b1= r * (Sy/Sx), how do I get the number for r (correlation) given the averages of X and Y and their standard deviations?

Answer 1

In getting the correlation of R where the given is the average of X and Y and calculate their standard deviation. So correlation coefficient is a number that quantities some type of correlation and dependence and the standard deviation are a quantity calculated to indicate the extent of deviation for a group as a whole. I hope this would help
