Frequently Asked Questions
Linear regression is a statistical method to model the relationship between a dependent variable (Y) and one independent variable (X) by fitting a linear equation to observed data.
The slope (b) indicates the change in Y for a one-unit change in X. The intercept (a) is the predicted Y value when X = 0.
R² (coefficient of determination) measures how well the regression line fits the data. Values close to 1 indicate a strong fit.
