Average variance extracted
In statistics (classical test theory), average variance extracted (AVE) is a measure of the amount of variance that is captured by a construct in relation to the amount of variance due to measurement error.

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.

Congeneric reliability
In statistical models applied to psychometrics, congeneric reliability \rho_C ("rho C") is the reliability of a unidimensional congeneric measurement model.

Construct (philosophy)
A construct in the philosophy of science is an ideal object, where the existence of the thing may be said to depend upon a subject's mind.

Covariance
In probability theory and statistics, covariance is a measure of the joint variability of two random variables.

Dichotomy
A dichotomy is a partition of a whole (or a set) into two parts (subsets).

Factor analysis
Factor analysis is a statistical method used to describe variability among observed, correlated variables in terms of a potentially lower number of unobserved variables called factors.

Generalizability theory
Generalizability theory, or G theory, is a statistical framework for conceptualizing, investigating, and designing reliable observations.

Internal consistency
In statistics and research, internal consistency is typically a measure based on the correlations between different items on the same test (or the same subscale on a larger test).

Intraclass correlation
In statistics, the intraclass correlation, or the intraclass correlation coefficient (ICC), is an inferential statistic that can be used when quantitative measurements are made on units that are organized into groups.

Kuder–Richardson Formula 20
In psychometrics, the Kuder–Richardson Formula 20 (KR-20), first published in 1937, is a measure of internal consistency reliability for measures with dichotomous choices.

Missing data
In statistics, missing data, or missing values, occur when no data value is stored for the variable in an observation.

Reliability (statistics)
Reliability in statistics and psychometrics is the overall consistency of a measure.

Robust statistics
Robust statistics are statistics with good performance for data drawn from a wide range of probability distributions, especially for distributions that are not normal.

Rule of thumb
The English phrase rule of thumb refers to a principle with broad application that is not intended to be strictly accurate or reliable for every situation.

Spearman–Brown prediction formula
The Spearman–Brown prediction formula, also known as the Spearman–Brown prophecy formula, is a formula relating psychometric reliability to test length and used by psychometricians to predict the reliability of a test after changing the test length.
