For Exercises find the coefficients of determination and non determination and explain the meaning of each.
r = 0.91
Given that r = 0.91 then Coefficient of Determination = r2 = (0.91)2 = 0.8281.
This result means that 82.81 % of the variation in the dependent variable is accounted for by the variations in the independent variable.
Coefficient of non – determination = 1 – r2 = 1 – 0.8281 = 0.1719.
Therefore 17.19% of the variation in the dependent variable is unexplained by the variations in the independent variable.
Therefore 17.19% of the variation in the dependent variable is unexplained by the variations in the independent variable.
