To calculate the y-intercept subtract Avg(Y) from Slope * AVG(X) To calculate the Slope of the Line, divide the SUM XY by SUM XX Multiple the between Avg(X)-X and Avg(Y)-Y and add the results: SUM XY = 37,918,000 Square the difference and add the result: SUM XX = 5, 800,000 Now, here we need to find the value of the slope of the line, b, plotted in scatter plot and. The equation of linear regression is similar to the slope formula what we have learned before in earlier classes such as linear equations in two variables. Measure the difference between the Average X and individual X Linear regression shows the linear relationship between two variables. There are several ways to find a regression line, but usually the least-squares regression line is used because it creates a uniform line. Y variable, in this case, it is Sale = 12600 A regression line, or a line of best fit, can be drawn on a scatter plot and used to predict outcomes for the (x) and (y) variables in a given data set or sample data.X variable, in this case, it is the Money Spent = 3300.Additionally, it is used to identify the subset of the independent variable that has an influence on the dependent variable. It helps to determine whether the variables have any relationship or not.

It can be applied when you want to understand the strength of the relationship between the independent and dependent variables. The model can be used as a predictive model when the goal of the analyst is prediction or error reduction. In general, its applications fall into two categories: Linear Regression is used in various industries. # Multiple Linear Regression: This model includes more than one independent variable # Simple Linear Regression : The model includes one independent variable This linear regression calculator uses X and Y values to determine the regression equation. Linear Regression further breaks down into two categories – Use the line regression calculator to find the regression equation. However, it was first published by Adrien-Marie Legendre in a scientific paper.Ī Linear Regression is useful to examine and establish a relationship between the two separate variables – independent or explanatory and dependent or response variables. Linear Regression is a form of statistical approach, allegedly invented by Carl Friedrich Gauss.
