WebA high R-squared and low p-value indicates that the independent variable explains a lot of the variation in the dependent variable and the linear relationship between the two variables is significant. High R-squared, High p-value. WebAs observed in the pictures above, the value of R-squared for the regression model on the left side is 17%, and for the model on the right is 83%. In a regression model, when the variance accounts to be high, the data points tend to fall closer to the fitted regression line.
