Quantitative Information Presentation and Gender: An Interaction Effect

Abstract

The authors investigated whether performance on mathematical test items would be influenced by an interaction between presentation format and gender. One hundred fourteen students in a management accounting course were randomly assigned either to a tabular format or to a graphics format. There were significant main effects for gender and presentation format; men outperformed women, and the subjects who received the tabular format outperformed the subjects who received the graphics format. A significant interaction supported the existence of a conditional relationship between performance on mathematical test items and presentation format. This relationship varied as a function of gender (symmetry permits the interchange of presentation format and gender). Simple effects for the interaction determined that the women who received the graphics presentation did not perform as well as their male counterparts, or as well as other women and men who received the tabular format. The results of this study indicate that presentation format is an important consideration in gender differences for mathematics performance.
