![]() Where Y and X are the mean of y and x data points respectively. So, the equation of the line of best fit for a given data is b = y - mx Find the y-intercept of the line using the formula: In the below line of best fit calculator, enter the different values for x and y coordinates and. Individual values within a line may be separated by. individual x, y values on separate lines. ![]() Data can be entered in two ways: x values in the first line and y values in the second line, or. x is the independent variable and y is the dependent variable. The trend line is also known as dutch line, or line of best fit, because it best represents the data on a scatter plot. Enter the bivariate x, y data in the text box. Find the slope of the best fit line using the formula:ģ. In the below Line of Best Fit Calculator enter different x,y co-ordinates and click calculate to generate the dutch line chart. Calculate the mean of x values and y values (X and Y)Ģ. Statisticians generally use the least-squares method to find the equation of the best fit line. The least-square method is a more accurate way of finding the line of best fit. Step 3: Click on "Reset" to clear the field and enter new data points.Step 2: Click on the "Calculate" button to find the best fit.Step 1: Enter the data points (x, y) in the space provided.NOTE: Each pair should be enclosed in a bracket separated by a commaįollow the steps given below to use the calculator: In this calculator, you can enter the data points of the given distribution and the equation of the best fit line will be calculated within a few seconds. Eg: rise in COVID-19 cases etc.Ī ' Line of Best Fit Calculator' is a free online tool that calculates the equation of the best fit line for the given data points. Exponential Best Fit Line: An exponential best fit line shows exponential growth.In the real world, data usually follows a polynomial trend. Polynomial Best Fit Line: A polynomial best fit line has many curves and bumps.Linear Best Fit Line: The line of best fit is a straight line when data points appear to be in a straight line.Line of best fit refers to a line that best expresses the relationship between a scatter plot of data points.
