Coefficient of Determination

The coefficient of determination is the primary way we can measure the extent, or strength, of the association that exists between two variables, X and Y. Statisticians interpret the coefficient of determination by looking at the amount of the variation in Y that is explained by the regression line. The coefficient of determination is defined by



















Thus, we can conclude that the variation in number of workers (the independent variable X) explains 97.76 percent of the variation in the production of Redwood falls plant (the dependent variable Y).
