Quality Evaluation Through Nomographs.
Wohlferd, Gerald
The Quality Measurement Project of New York State, in an attempt to simplify the assessment of school effectiveness, has applied nomographic techniques to this process. Essentially a nomograph is an easy graphic method of obtaining a predicted score without the use of the original regression equation upon which it is based. In the case herein described. the average reading score (grades 5 and 8), average arithmetic score (grade 5), and average composite score (grade 5) on the Iowa Tests of Basic Skills, Form 4 may be predicted from average IQ, average mother's education, and instructional costs. Likewise average arithmetic score (grade 8) may be predicted from mother's education, father's education, and IQ and average composite score (grade 8) from father's education, IQ, and instructional costs. The computation of each of these variables for use on the included nomographic charts is described. The process of entering these figures on the charts and obtaining the predicted score (a matter of drawing two or three lines) is explained. Once the predicted score has been obtained, it may be compared with the actual average score and school effectiveness may be assessed by use of the standard error. This process is also described. For a description of the study and the statewide norm tables upon which the nomographs are based see TM 000 316. (DG)
