Determining School Effectiveness Following a Regression Analysis.
Convey, John J.
Three methods that can be used subsequent to a regression analysis to determine the relative effectiveness of schools are Dyer's Performance Indices, Scheffe's hyperbolic confidence bands, and Gafarian's linear confidence bands. These methods were applied to data from 54 hypothetical schools randomly generated from a multivariate normal distribution using parameters from previous studies. Data points having Performance indices of 1 and 5 generally fell outside of the Scheffe confidence bands. The linear confidence bands were much wider than the Scheffe bands near the mean and slightly narrower at the extremes. Overall, Performance Indices and Scheffe bands produced similar results.
