The coefficient of determination, often denoted R2, is the proportion of variance in the response variable that can be explained by the predictor variables in a regression model.
This calculator finds the coefficient of determination for a given regression model.
Simply enter a list of values for x (the predictor variable) and y (the response variable) in the boxes below, then click the “Calculate” button:
x (Predictor Variable)
y (Response Variable)
Coefficient of Determination (R2): 0.8368
Interpretation: 83.68% of the variation in the response variable can be explained by the predictor variable.
