How to find r statistics

For the calculation of R squared, you need to determine the Correlation coefficient, and then you need to square the result. R Squared Formula = r2 Where r the correlation coefficient can be calculated per below: r = n (∑xy) – ∑x ∑y / √

How to find the correlation coefficient (r) using your graphing

It always lie between -1 and +1 which represented by -1 ≤ r (X, Y) ≤ 1. if r (X, Y) = 1 then the variables X and Y are positively correlated. if r (X, Y) = -1 then the variables X and Y are negatively correlated. if r (X, Y) = 0 then there is no
