A regression equation used to predict X from Y is known as the regression equation of:
Correct answer: B. X on Y
- A. Y on X
- B. X on Y
- C. X and Y jointly
- D. The means on the variances
Explanation
The phrase regression of X on Y means that X is the dependent or predicted variable and Y is the explanatory variable. Regression of Y on X reverses these roles and generally gives a different line.

About Correlation and Regression
Correlation describes the direction and strength of association between two variables using scatter diagrams and correlation coefficients. Regression covers fitted lines, regression equations, prediction and least squares, with a clear distinction between association and causation and between estimating a response value and reversing the roles of the variables.
