Product Moment Coefficient (r)
This gives an indication of the strength of the linear relationship among two variables.
Note that this formula can be rearranged to have different outlooks however the resultant is always the similar.
Illustration
Given data was observed and it is required to establish if there exists a relationship among the two.

Solution
Calculate the product moment coefficient of correlation r:
Hence the correlation coefficient indicates a strong negative linear association among the two variables.
Q. How to plot Line Graphs? Ans. Line graphs can be useful in analyzing data. They are particularly helpful when you are interpolating or extrapolating information from y

Proof of: if f(x) > g(x) for a x b then a ∫ b f(x) dx > g(x). Because we get f(x) ≥ g(x) then we knows that f(x) - g(x) ≥ 0 on a ≤ x ≤ b and therefore by Prop
