Abstract
In the last section, correlation was discussed as a measure describing linear relationship between 2 variables [1]. Regression is another method describing their relationship by using a regression line which is the best fitting straight line that we can draw through data points on a scattered plot. Correlation depicts the direction and strength of the relationship, while regression provides explanation or prediction of the response variable (Y) using one or more predictor variables (X).
