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.
Used in course? Yes
Time spent reviewing site: An hour on my own time and then in a class lesson, probably about 20 minutes.
