Determine the coefficient of determination
WebJun 24, 2024 · To square the r-value, multiply the value by itself. For instance, if you have the correlation coefficient of r = -0.35, squaring this value gives you the coefficient of determination: r2 = (-0.35) (-0.35) = 0.1225. 4. Evaluate the results. Convert the coefficient of determination to a percent and evaluate the data. WebIn statistics, the coefficient of determination, denoted R 2 or r 2 and pronounced "R squared", is the proportion of the variation in the dependent variable that is predictable …
