#USE EXCEL TO CALCULATE LINEAR REGRESSION EQUATION HOW TO#

A scatter chart will be plotted inside the worksheet.First, select columns from the table and choose the Scatter chart from the Insert option.In this method, we will plot a scatter chart to show a least squares regression line in Excel. Then, the line of best fit is added to the chart by using the linear regression equation to calculate the y-values of the line for a range of x-values.

When plotting a scatter chart to show a least squares regression line, the data points are first plotted on the chart. Using Scatter Chart to Plot Least Squares Regression Line Suppose we have a month-wise dataset of Temperature Rise (☏) and Air Conditioners Sold (in thousands).ġ. Among them, the first method is using Scatter Chart to plot the least squares regression line, the second method deals with an arithmetic formula, and the rest methods involve the utilization of Excel built-in functions to calculate the least squares regression line in Excel. In the following, I have shared 5 simple examples to get the least squares regression line in Excel.

How to Plot Least Squares Regression Line in Excel: 5 Easy Ways

It can be used to make predictions about future values of the dependent variable based on the independent variable. The line of best fit represents the average trend in the data. It is called “ Least Squares” because the method involves finding the line that minimizes the sum of the squared differences between the observed data points and the corresponding predicted values of the line. The least squares regression line is a statistical tool used to model the relationship between two variables. Related Articles What Is Least Squares Regression Line?
