          By playing with the dots, you can see that, when there are multiple variables involved, the true relationships can be very counterintuitive. That's why we have statistics: to make us unsure about things.

          Below, see if you can choose the betas to minimize the sum of squared errors.

          There are many other prediction techniques much more complicated than OLS, like logistic regression, weighted least-squares regression, robust regression and the growing family of non-parametric methods.
