When taking into account the variables for a study into how students of different demographics demonstrate a gap in educational outcomes, one idea to consider is the interaction between demographic variables. In this article and others, there seemed to be no interaction effect in study habit differences for students of different ages and gender. Perhaps more in-depth research is necessary in comparing students of different genders, by taking into account other variables such as socioeconomic status, ethnicity, and so on, and seeing if there are effects when two or more variables interact.
