Desmos line of best fit
Using this Desmos eTool we let students try to move the line into the "best" spot (be sure you hide the line of best fit to start). They discovered that the the line of "best" fit is the one that minimizes the sum of the squared residuals (the least squares regression line!). This can also be done nicely using the statistical software ...Using Desmos.com to calculate a curve of best fit.Linear regression is used to model the relationship between two variables and estimate the value of a response by using a line-of-best-fit. This calculator is built for simple linear regression, where only one predictor variable (X) and one response (Y) are used. Using our calculator is as simple as copying and pasting the corresponding X and Y ...
