It indicates the level of variation in the given data … WebUse the value of the correlation coefficient r to calculate the coefficient of determination r 2. What does this tell you about the explained variation of the data about the regression line? About the unexplained variation? r = 0.386 Calculate the coefficient of determination. (Round to three decimal places as needed.)
The coefficient of determination (R²) measures how well a statistical model predicts an outcome. The outcome is represented by the model’s dependent variable. The lowest possible value of R² is 0 and the highest possible value is 1. Put simply, the better a model is at making predictions, the closer its … See more You can choose between two formulas to calculate the coefficient of determination (R²) of a simple linear regression.
