WebFeb 22, 2024 · We can also calculate the R-squared of the regression model by using the following equation: R-squared = SSR / SST R-squared = 279.23 / 316 R-squared = 0.8836 This tells us that 88.36% of the variation in exam scores can be explained by the number of hours studied. Additional Resources WebFor simple linear regression, the least squares estimates of the model parameters β 0 and β 1 are denoted b0 and b1. Using these estimates, an estimated regression equation is constructed: ŷ = b0 + b1x . The graph of the estimated regression equation for simple linear regression is a straight line approximation to the relationship between y and x.
