The denominator in the calculation of the sample covariance,cov (x,y) ,is:

A) n − 2
B) n − 1
C) n
D) 2n − 1

Sample Covariance

A measure of the degree to which two variables change together for a sample of a population, indicating their linear relationship.

Cov (x,y)

Represents the covariance between two variables \(x\) and \(y\), measuring how changes in one variable are associated with changes in another.
