Statistical Analysis of Questionnaires: A Unified Approach Based on
R and Stata presents special statistical methods for analyzing data
collected by questionnaires. The book takes an applied approach to
testing and measurement tasks, mirroring the growing use of
statistical methods and software in education, psychology,
sociology, and other fields. It is suitable for graduate students
in applied statistics and psychometrics and practitioners in
education, health, and marketing. The book covers the foundations
of classical test theory (CTT), test reliability, validity, and
scaling as well as item response theory (IRT) fundamentals and IRT
for dichotomous and polytomous items. The authors explore the
latest IRT extensions, such as IRT models with covariates,
multidimensional IRT models, IRT models for hierarchical and
longitudinal data, and latent class IRT models. They also describe
estimation methods and diagnostics, including graphical diagnostic
tools, parametric and nonparametric tests, and differential item
functioning. Stata and R software codes are included for each
method. To enhance comprehension, the book employs real datasets in
the examples and illustrates the software outputs in detail. The
datasets are available on the authors' web page.
