Most would wind up working on office desktops for which they would not be an administrator. Downloading R would not be an option and R would be steep learning curve for some for whom computers are an unfamiliar technology.
Spreadsheet based statistics, for all the faults and potential for error, would be at the center of the course. The use of Ubuntu in the classroom meant using LibreOffice.org or Gnumeric. Gnumeric provided the capability of including box and whisker plots. A change in computer laboratory technology to Microsoft Windows five years later saw the use of Gnumeric on Windows - until Gnumeric stopped supporting Windows.
