Regression line: the best-fitting straight line through a set of points in a scatter diagram. Regression coefficient (b): is the slope of the regression line: can be expressed as the ratio of the sum of squares for the covariance to the sum of squares for x. Sum of squares: the sum of squared deviations around the mean.
