Non-White, No More: Effect Coding as an Alternative to Dummy Coding with Implications for Higher Education Researchers
Mayhew, Matthew J.; Simonoff, Jeffrey S.
Journal of College Student Development, v56 n2 p170-175 Mar 2015
The purpose of this article is to describe effect coding as an alternative quantitative practice for analyzing and interpreting categorical, race-based independent variables in higher education research. Unlike indicator (dummy) codes that imply that one group will be a reference group, effect codes use average responses as a means for interpreting information. This technique is especially appropriate for examining race, as such a process enables raced subgroups to be compared to each other and does not position responses of any raced group as normative--the standard against which all other race effects are interpreted. The issues raised here apply in any research context where a categorical variable without a natural reference group (e.g., college major) is a potential predictor in a regression model.
