Question 366155: The best-fit line (or regression line) on a scatter diagram is a line that lies closer to the data points than any other possible line (according to a standard statistical measure of closeness). Why do we need to distinguish between strong and weak correlation of data sets using best-fit lines? When a correlation has been established between the two data sets, how is it linked to causality?

A correlation that is close to -1 or 1 shows that there's a bigger chance of causality (as opposed to a correlation that's closer to 0)
