WebFeb 22, 2024 · SST = SSR + SSE. 1248.55 = 917.4751 + 331.0749. We can also manually calculate the R-squared of the regression model: R-squared = SSR / SST. R-squared = 917.4751 / 1248.55. R-squared = 0.7348. This tells us that 73.48% of the variation in exam scores can be explained by the number of hours studied. WebJan 17, 2024 · Minimizing residuals.
