Abstract
Subjects analyzed data from typical ANOVA designs using three different computer programs. Several measures of cost, completion, and ease of program use were recorded and compared in a repeated measures Latin square design. Within time constraints and support that simulate an instructional setting, subjects could not answer the research questions using two traditional computer packages, but subjects completed all analyses using an interactive personal computer program designed to minimize computer-related difficulties. Such results can be useful in guiding design of instructional strategies and computer programs.
