Star plots are useful in that they observe the behavior of all variables in a test. A star plot is set up with equal angular points, each of which represents a variable. The data is represented by different colored lines that disperse toward the point of the star that the data most heavily favors. The star map below is a graphical analysis of a literary test taken by a student.
