| 520 | |a The Feasibility of developing an index to represent the degree of consistency with which a student responds to a set of items in a homogeneous scale is investigated. The dispersion of responses to a set of items by a group of subjects has typically been measured by the standard deviation. Here, the interest is in the dispersion of responses from the same subject to a set of items. The Ohio Vocational Interest Survey was used to gather students' responses to 11 items (job-activity statements) in terms of a 5-option scale. The investigation consisted of 3 phases: (1) a scale clarity index (SCI) was devised; (2) all possible response patterns were defined and the clarity of each was rated in terms of degree of consistency; and (3) the extent to which the deviation raw score, the standard deviation, mean deviation, and a centrality index would predict the scale clarity rating developed in the second phase was investigated. A critical aspect of this study is the judges' ratings of the clarity inherent in each pattern. The SCI provides additional information as to the nature of a subject's responses, is useful in the interpretation of raw scores, especially those based on individual item responses, and has great promise in testing and measurement practice.
