Regression is a statistical method used to examine and measure the relationship between a dependent variable and one or more independent variables. It helps a researcher determine how changes in one variable are associated with changes in another variable and also helps in predicting the value of the dependent variable. In simple linear regression, the relationship between two variables is represented by an equation such as (Y=a+bX+e), where (Y) is the dependent variable, (X) is the independent variable, (a) is the intercept, (b) is the regression coefficient, and (e) represents the error term.
