- The regression line is a straight line that describes the behavior of a set of data or the trend of a given set of data.
- It is useful in forecasting the procedures.
- The purpose of the regression line is to explain the interrelation of a dependent variable i.e., Y variable with an independent variable i.e., X variable.
- By using the regression line, the future behavior of the dependent variable can be analyzed by using different independent variables.
The regression line can be calculated by using the formula:
Y = a + bx + u
Where,
- Y represents the dependent variable
- X represents the independent variable
- a represents the interception point
- b represents the slope
- u represents the residual regression
The regression line helps in estimating the change in y for a one-unit change in x.
