A number that summarizes or captures some aspect of a person's performance in the carefully selected and observed behavior samples that make up psychological tests.

Formulas used to calculate interitem consistency.
What are Kuder-Richardson formula 20 and coefficient alpha (Cronbach's alpha)?
100
The extent to which a test measures what it purports to measure.
What is validity?
200
A group of several tests, or subtests, that are administered at one time to one person.
What is a battery?
200
Organizing raw data in some sensible way so that they can be inspected.
What is frequency distribution.
200
Uses standards based on the performance of specific groups of people to provide information for interpreting scores.
What is norm-references test interpretation?
200
Inclusion of items rf sets of items that tap content knowledge or psychological functions that differ from those tapped by items in the same test.
What is content heterogeneity?
200
A standard on which a judgment or decision may be based, or a characteristic mark or trait.
What is criterion?
300
A questionnaire developed during World War I to screen recruits who might suffer from mental illnesses.
What is the Woodworth Personal Data Sheet?
300
The value that divides a distribution that has been arranged in order of magnitude into two halves.
What is the median?
300
They reflect nothing more that the average performance of certain groups of test takers of specific age levels, at a given time and place, on a specific test.
What are mental age norms?
300
An extension of classical test theory that uses analysis of variance methods to evaluate the combined effects of multiple sources of error variance on test scores simultaneously.
What is generalizability theory?
300
A table that displays the intercorrelations among the scores obtained by a sample of individuals on a wide variety of tests (or subtests or items).
What is a correlation matrix.
400

Variables such as time, distance, and temperature, that have infinite ranges and really cannot be counted.
What are continuous variables?
400
Indicates the relative location of a score within a distribution.
What is a z score?
400
Provide intervals for obtained scores that alert test users to the fact that scores are subject to fluctuation due to measurement error.
What are standard errors of measurement?
400
(a) to reduce the number of dimensions needed to describe data from a set of measured variables and (b) to investigate the structure that accounts for the interrelationships between the variables, in order to classify them and better understand the nature of the information that they provide.

500
This method applies mathematical models to test item data from large and diverse samples.
What is item response theory?
500
Reliability data used to derive probability statements concerning the likelihood that the obtained differences between scores, and what the scores represent, could have been due to chance.
What is the standard error of the difference between scores?
500
Requires the collection of data on two or more distince traits by two or more different methods.
