The Easy Way to Solve Problems in Regression

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.

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.
