The Initial Development of a Technique for Deriving Additional Information from Test Performance. Final Report.
Wick, John W.
A pattern-analytical technique, Similar Response Analysis (SRA), was developed, validated with contrived data, verified using previously reported data based on other pattern-analytical methods, and used successfully with "real" data. This technique orders subjects on the basis of the similarity of responses of adjacent individuals, not on the basis of the number of times each individual marks the answer keyed as "correct." The technique is offered as an alternative method for ordering a list of students on the basis of test scores. SRA is based on the theory of minimum inversions; i.e., if the number of matched responses decreases as subjects are further removed from one another in the list, no inversions will occur. However, when subjects A and B, adjacent to one another in the list, have fewer matched responses than A and C who are not adjacent, then an inversion occurs. The technique is designed to order the subjects so that only a minimum number of inversions can occur. The theory upon which SRA is based is discussed and a computer program for the technique is presented. (Author/ES)
