Definitions:

Sample Coefficient

A numerical measure that describes some characteristic or aspect of a sample of data.

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.

Covariance

A statistical measure that indicates the extent to which two variables change together; if the greater values of one variable mainly correspond with the greater values of the other variable, and the same holds for the lesser values, the covariance is positive.
