Ideal point discriminant analysis is a classification tool which uses highly intuitive multidimensional scaling procedures. However, in the last paper, Takane wrote about it. He concludes that the interpretation is rather intricate and calls that a weakness of the model. We summarize the conditions that provide an easy interpretation and show that…

Let X be a statistical variable representing student ratings of University teaching. It is natural to assume for X an ordinal scale consisting of k categories (in ascending order of satisfaction). At first glance, student ratings can be summarized by a location index (such as the mode or the median of X) associated with a convenient measure of…

Multidimensional scaling (MDS) and its potential use for research and evaluation in health-related professions are discussed. Useful data types, interpretation of results, and various applications of MDS are presented. MDS is less restrictive than factor analysis since it does not assume a linear relationship between the objects/variables of…

A model of graph comprehension is proposed including perceptual and memory processes. Multidimensional scaling (MDS), cluster analysis, and analysis of variance (ANOVA) were used to determine how college students with different mathematical experience read different types of bar graphs. Data were collected at the University of Oklahoma (Norman)…

Concept mapping is a structured conceptualization that can be used by groups to develop a conceptual framework that guides evaluation or planning. Twelve papers discuss concept mapping in evaluation/planning in terms of theory development; measurement, construct validity, and pattern matching; outcome assessment and internal validity;…

Since educational statistics, which are relatively easy to obtain, can only attempt to measure "quality," this paper asks how quality in higher education is assessed and how educational rankings, which are defined as benchmarks or attempts to measure, contribute to this process. The paper notes that while attempts to rank institutions of…
