In a regression analysis if r 2 1 then
If the R2 is between 0 and 1, the model allows you to partially predict exam scores. The model’s estimates are not perfect, but they’re better than simply using the average exam score. If the R2 is 1, the model allows you to perfectly predict anyone’s exam score. More technically, R2 is a measure of goodness of fit. See more 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 … See more You can choose between two formulas to calculate the coefficient of determination (R²) of a simple linear regression. The first formula is specific to … See more If you decide to include a coefficient of determination (R²) in your research paper, dissertation or thesis, you should report it in your results section.
