fig005: Item map of all subjects and positively phrased items only.

Mentions: The Winsteps program produced a comprehensive snapshot of the findings in the form of person-item maps. Figures 4, 5, and 6 which are based on similar one produced by the Winsteps, provide a unified synopsis of the results obtained for persons and items. The map illustrates a continuum of person attitude and item difficulty constructed by the analysis. Persons and items are both calibrated on the same scale. The unit of measurement on this scale is the logit which is obtained by a simple logarithmic transformation of the probability of receiving a particular rating. If the data fit the model the logit defines an equal-interval scale, which serves as a common frame of reference for the analysis, thus facilitating comparisons within and between persons and items. The logit scale is displayed in the first column of the variable map. The second column of the map displays the distribution of person measures, which in this case represent estimates of person perceptions toward the use of hearing aids. Each square is equivalent to 5 respondents, and each dot represents less than 5 respondents. The distribution of person measures spans the length of 6.03 logits. Person measures are ordered with the highest values appearing at the top of the column, and the lowest values appearing at the bottom of the column. In this column, high person measures, which were obtained though the transformation of high raw score totals, represent persons with positive attitudes toward hearing aids. Low person measures, which were obtained through the transformation of low raw score totals, represent persons with negative attitudes toward hearing aids.
