Scatterplots: Estimating the Line of Best Fit Mathematics Instructional Plan
Determining Lines of Best Fit - Mathematics Instructional Plan
This lesson has students complete a basketball activity and then use the data from the activity to create a scatterplot. Once they create their scatterplot they determine correlation and draw a line of best fit.
With your mouse, drag data points and their error bars, and watch the best-fit polynomial curve update instantly. You choose the type of fit: linear, quadratic, cubic, or quartic. The reduced chi-square statistic shows you when the fit is good. Or you can try to find the best fit by manually adjusting fit parameters.
