GraphLab teaches basic principles and skills for graphing. The program is divided into four lessons: scaling, drawing a "best-fit" straight line, errors, and least-squares fit.
Scaling: Requires students to set the scales for graphs in which the variables that involve direct and inverse proportions and in which the scale involves exponents. Students must provide equally spaced intervals.
