Index Construction Using Principal Component Analysis: An Application in Primary Education in India. Sage Research Methods Cases Part 1
Direct linkDirect link
Tamal Krishna Kayal – Sage Research Methods Cases, 2023
Performance in primary education can be measured in terms of different variables, like enrolment rate, attendance rate, or levels of learning achievement of students. Thus, for an analysis of the comparative performance of units, like country, state, or district, we need an aggregate measure or an index developed from these variables. In…

Getting Busy Teachers to Do a Card Sort: Using Q Methodology Online to Research Teacher Viewpoints. Sage Research Methods: Doing Research Online
Direct linkDirect link
Jennifer Shearman – Sage Research Methods Cases, 2022
This case study describes a Q methodology study which captured and analyzed the viewpoints of 45 UK teachers online. The teachers might liken their participation in the study to a "card sort" activity: their relative placement of statement cards revealed their opinions of mastery in mathematics. Factor analysis of the completed sorts…

Exploratory Factor Analysis as a Tool for Investigating Complex Relationships: When Numbers Are Preferred over Descriptions and Opinions. Sage Research Methods Cases Part 1
Direct linkDirect link
Stephen D. Oller – Sage Research Methods Cases, 2014
Exploratory Factor analysis is a research tool that can be used to make sense of multiple variables which are thought to be related. This can be particularly useful when a qualitative methodology may be the more appropriate method for collecting data or measures, but quantitative analysis enables better reporting. This case first gives a brief…

Factor Analysis: The Way to Uncover Dimensions of a Scale. Sage Research Methods Cases Part 1
Direct linkDirect link
Baoshan Zhang; Qianyun Gao; Yanling Bi; Guoliang Yu – Sage Research Methods Cases, 2014
In 2007, while pursuing my doctoral degree, I (Baoshan Zhang) embarked on a study to develop a scale for measuring state self-monitoring. Although a Self-Monitoring Scale had been developed in 1974 to measure stable individual characteristics, the measure could be inadequate for examining the short-term self-monitoring elicited by certain social…

From Measurement to Modeling: A Case Study of the Development and Implementation of the Adaptability Scale. Sage Research Methods Cases Part 1
Direct linkDirect link
Andrew J. Martin; Harry Nejad; Susan Colmar; Gregory Arief D. Liem – Sage Research Methods Cases, 2014
This case study describes a program of research that developed a new measure--the Adaptability Scale--and then tested this new measure through a set of substantive research questions and publications. Three phases of this research program are detailed: a measurement phase, a modeling phase, and a mediation phase. The aim of this case study is to…

TETREST: A Fortran IV Program for Calculating Tetrachoric Correlations. Research Report 75-2.
PDF on ERIC Download full text
McBride, James R.; Weiss, David J. – 1975
A general purpose computer program for the calculation of a matrix of tetrachoric correlations is described. This program was developed for use in adaptive (and other) testing research for examining the unidimensionality assumption in latent trait theory, in conjunction with available factor analysis programs. Several other potential applications,…
