  • None of the four models fits well, although the students favored the logarithmic fit. The logarithmic model may be a best fit, but the function cannot handle x = 0, starts too fast, and, possibly most problematic, the speed continues to rise without limit. Sprinters hit a maximum speed and then attempt to hold that speed into the finish line.

    Dec 03, 2020 · The line of best fit best describes the points on a scatter plot when the average difference between where the line is drawn and the closest point is the least. This is easy to check with the least square method. Equations are sometimes used to describe the lines as a function when only one point will relate to a point on the line of best fit.

    You can use this Linear Regression Calculator to find out the equation of the regression line along with the linear correlation coefficient. It also produces the scatter plot with the line of best fit. Enter all known values of X and Y into the form below and click the "Calculate" button to calculate the linear regression equation.
