A quadratic regression is the process of finding the equation of the parabola that best fits a set of data. Quadratic Regression Equation y a x2 b x c a S x 2 y S xx - S xy S xx 2 S xx S x 2 x 2 - S xx 2 2 b S xy S x 2 x 2 - S x 2 y S xx 2 S xx S x 2 x 2 - S xx 2 2 c S y n - b S x n - a S x 2 n. Using a calculator to perform a quadratic regression.
A quadratic regression models a relationship using a single curve such as the too much of a good thing effect.
