Define correlation and regression and explain the relationship between correlation and regression coefficients.

Correlation and Regression Differences

There are some differences between Correlation and regression.

Correlation shows the quantity of the degree to which two variables are associated. It does not fix a line through the data points. You compute a correlation that shows how much one variable changes when the other remains constant. When r is 0.0, the relationship does not exist. When r is positive, one variable goes high as the other goes up. When r is negative, one variable goes high as the other goes down.
