How do i interpret r squared
WebR-squared is comparing how much of true variation is in fact explained by the best straight line provided by the regression model. If R-squared is very small then it indicates you should consider models other than straight lines. • ( 6 votes) tbeatty 11 years ago WebR-Square – R-Square is the proportion of variance in the dependent variable ( science) which can be predicted from the independent variables ( math, female, socst and read ). This value indicates that 48.9% of the variance in science scores can be predicted from the variables math, female, socst and read .
