Analysis of variance

Analysis of variance (ANOVA) is a collection of statistical models and their associated estimation procedures (such as the "variation" among and between groups) used to analyze the differences among means.

See Generalizability theory and Analysis of variance

Classical test theory

Classical test theory (CTT) is a body of related psychometric theory that predicts outcomes of psychological testing such as the difficulty of items or the ability of test-takers. Generalizability theory and Classical test theory are statistical theory.

Goldine Gleser

Goldine C. Gleser (1915 – 2004) was an American psychologist and statistician known for her research on the statistics of psychological testing, on generalizability theory, on defence mechanisms, on the psychological effects on child survivors of the Buffalo Creek flood, for her work with Mildred Trotter on estimation of stature, and for her participation in the Cincinnati Radiation Experiments.

Item response theory

In psychometrics, item response theory (IRT) (also known as latent trait theory, strong true score theory, or modern mental test theory) is a paradigm for the design, analysis, and scoring of tests, questionnaires, and similar instruments measuring abilities, attitudes, or other variables.

Lee Cronbach

Lee Joseph Cronbach (April 22, 1916 – October 1, 2001) was an American educational psychologist who made contributions to psychological testing and measurement.

Observation

Observation in the natural sciences is an act or instance of noticing or perceiving and the acquisition of information from a primary source.

See Generalizability theory and Observation

Reliability (statistics)

In statistics and psychometrics, reliability is the overall consistency of a measure.
