The Graphical Representation of Quantitative Research Synthesis Residual Variation.
Ludlow, Larry H.
Educational and Psychological Measurement, v47 n4 p941-51 Win 1987

Graphical representations of data on techniques for teaching composition skills are used to help determine the extent to which sample estimates deviate from modeled population estimates. (TJH)
