Effect Sizes in Qualitative Research.
Onwuegbuzie, Anthony J.
The American Psychological Association Task Force recommended that researchers always report and interpret effect sizes for quantitative data. However, no such recommendation was made for qualitative data. The first objective of this paper is to provide a rationale for reporting and interpreting effect sizes in qualitative research. Arguments are presented that effect sizes enhance the process of "verstehen/hermeneutics" advocated by interpretive researchers. The second objective of the paper is to provide a typology of effect sizes in qualitative research. Examples illustrating various applications of effect sizes are given. For instance, when conducting topological analyses, qualitative analysts only identify emergent themes, yet these themes can be "quantitized" to determine the hierarchical structure of emergent themes. The final objective of this discussion is to illustrate how inferential statistics can be used in qualitative data analysis. This can be accomplished by treating words spoken by individuals or observations emerging from a particular setting as sample units of data that represent the total number of words or observations existing from that sample member or context. Heuristic examples are provided to demonstrate how inferential statistics can be used to provide more complex levels of "verstehen" than is presently found in qualitative research.
