The "k"-means clustering method, while widely embraced in college student typology research, is often misunderstood and misapplied. Many researchers regard "k"-means as a near-universal solution for uncovering homogeneous student groups, believing its success hinges primarily on the selection of an appropriate "k."…

ABC analysis is a well-established categorization technique based on the Pareto Principle for determining which items should get priority in the management of a company's inventory. In discussing this topic, today's operations management and supply chain textbooks focus on dollar volume as the sole criterion for performing the categorization. The…

Previous research on sensation seeking (SS) was dominated by a variable-oriented approach indicating that SS level has a linear relation with a host of problem behaviors. Our aim was to provide a person-oriented methodology--a probabilistic clustering--that enables examination of both inter- and intra-individual differences in not only the level,…

Individuals were grouped into person clusters on the basis of the similarity of their inventory profiles. In any particular profile cluster, homogeneous groups (by curriculum areas) of individuals tend to group into attraction patterns (presence in profile cluster) and avoidance patterns (absence from profile cluster).

Seventy-two first grade students and 72 freshman college students participated in a study designed to test the hypothesis that the younger the child, the more perceptible are the attributes used in judging equivalence in sorting tasks. (BD)

Two experiments explored the differential effects of two kinds of organization (taxonomic and schematic) on retrieval of information. (Author/PN)

Compares two basic variants of the sorting method: single-sort and multiple sort. The nature of individual differences in sorting, as well as sex differences, were also investigated. Stimulus materials were the 15 mutually exclusive kinship terms selected by Wallace and Atkins (1960). (RC)

This explorative data mining project used distance based clustering algorithm to study 3 indicators, called OIndex, of student behavioral data and stabilized at a 6-cluster scenario following an exhaustive explorative study of 4, 5, and 6 cluster scenarios produced by K-Means and TwoStep algorithms. Using principles in data mining, the study…

An exploration of age-related characteristics of children's personal categorizing schemes and relationships between free recall clustering (measured in reference to these schemes), and the number of items recalled. The 60 subjects were from five grade levels: 1, 4, 7, 10 and college. (Author/SDH)

This study was designed as the first in a series of inquiries to investigate the use of multidimensional scaling techniques for observing and measuring underlying dimensions commonly perceived by viewers. Following a preliminary study to select photographs, 15 university students aged 19 to 45 were presented with stimuli consisting of 34 colored…

Investigations designed to eliminate ambiguities in the Andre and Kulhavy procedure and to investigate the effects of noun modifications and sentence voice in the category clustering of sentences were conducted. Two experiments were carried out; both employed a mixed factorial design and were prepared in dittoed booklets. The Ss were run in…
