Triangle Plots: Graphic Display of "Just Right" Scale Data
Abstract:
Data gathered in this fashion are typically summarized by dividing responses to the "just right" scale into three categories: "too little," "just right" and "too much," and then determining the percentage of responses falling into each of the three categories. The intent is to develop and compare profiles of the products being tested. When numerous characteristics are involved, tabular approaches to this task can be unwieldy, especially if several products are involved. This paper presents a graphical technique for displaying such profiles, thus facilitating product comparisons and the assessment of test product strengths and weaknesses. The technique is called the triangle plot.
