A coefficient in literal form in an algebraic term is called a literal coefficient.

Correlation Coefficient. A number that is a measure of the strength and direction of the correlation between two variables. Correlation coefficients are expressed using the variable r, where r is between 1 and â1, inclusive. The closer r is to 1 or â1, the less scattered the points are and the stronger the relationship. Only data points with a scatterplot which is a perfectly straight line can have r = â1 or r = 1.
