I thought it was one of the most user friendly applications for linear regression. I liked that the students had the ability to move the potential least squares line to what they might think it would be and then have the actual prediction line post. I also have concerns about the formula used for the outlier section. I skipped that part of the application because I did not want to confuse my students.

Technical Remarks:

When plotting points, after clicking the box to plot points, I would have the program clear out the entry field in order to add new points. This way there is no confusion about what has been entered.
Time spent reviewing site: An hour on my own time and then in a class lesson, probably about 20 minutes.
