This statistics text utilizes LibreOffice.org Calc and Gnome Gnumeric to make statistical calculations and box plots. Both Calc and Gnumeric are open source, cross-platform software and can be downloaded from their respective web sites.
I don’t know why, but, occasionally, people may have to do minimal or even considerable statistical calculations using Calc, the OpenOffice.org‘s spreadsheet part of the Office Productivity Suite. Although, I wouldn’t recommend doing so since there are other, better software packages to complete simple and complex statistical analyses, such as R, a statistical programming language and environment with excellent analysis and graph capabilities. R can be found at one of its many mirrors.
