This is a free program taken from a CD-ROM collection of over 200 mathematics puzzles, available on the developer's Web site. Developed by a veteran teacher, these visually-oriented puzzle games have a simple interface and are designed to provide math programs in context to middle-school (grades five through nine) students.
In this particular program, students use sets of data to construct on-screen box and whisker plots. The screen layout has been improved: information about the box & whisker plot is more closely tied to the plot itself. The help screen has been improved.
