Measuring Equity in Educational Effectiveness Research: The Properties and Possibilities of Quantitative Indicators
Kelly, Anthony
International Journal of Research & Method in Education, v38 n2 p115-136 2015
There has never been a published discursive review of equity measurement methodology in educational effectiveness research, though the literature on equity is growing. This paper sets out several indices that have the potential to measure it in terms of pupil attainment or in terms of how far a school (or group of schools) is from having a "fair" proportion of its success attributable to a "fair" proportion of its student population. The paper explores the principles and properties of three relatively simple metrics (the "Range Ratio" family of measures, the "Coefficient of Variation" and "McLoone's Index") leading to two complex measures ("Theil's T" and finally to the Gini-based "Attainment Equity Index"). The paper investigates the warrant that the measures have (or do not have) for measuring equity by exploring them in a theoretical way so that their strengths, provenances and presumptions reveal themselves, and concludes with a discussion--the first of its kind in educational effectiveness research--on their desirable characteristics and properties. Worked examples from 2009 to 2011 UK pupil attainment data are presented in the Notes by way of worked illustrations, as are another two indices: the "Variance of the Logs" and the "Atkinson Index."
