What to do when you have to solve problems on Regression.
These problems are taught and used at the High School and College Level.
We start with a basic problem on Regression where you learn that the arithmetic means of x and y are obtained by solving the Regression equations simultaneously.
Regression Problem 1
Next, you will learn how to calculate the Regression coefficients and the correlation coefficient from the 2 lines of Regression. Note that this method works by trial and error.
