Understanding Best-Fit with a Visual Mode: Measuring Error in a Linear Model

This Understanding Best-Fit with a Visual Mode: Measuring Error in a Linear Model interactive also includes:

Reduce the error. The interactive allows users to graph the line of best fit for five data points. Pupils manipulate the line and find the measure of error using three different methods. By comparing the different methods, learners find the line that minimizes the error.
