Outliers and Accountability, Fact or Fiction?
Brager, Gary L.
The present paper sought to investigate the usefulness to accountability of identifying outlying schools through multiple regression. The outlier approach identifies schools which differ significantly for reasons other than variation in the predictors. The present study was not able to confirm the construct validity of the outlier approach for the author's school system. That is, educational process variables (observations, interviews, school size, staff ratios, ability scores, etc.) did not discriminate the positive from the negative outliers. Moreover, the study showed the outlier approach may be merely a tautology (i.e., 5% of the schools are outliers at the 5% level of significance.) (Author)
