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.
What is a raw score?
100
The two most frequently used formulas used to calculate interitem consistency
What are the Kuder-Richardson formula 20 and coefficient alpha, also known as Cronbach's alpha?
100
The extent to which a test measures what it purports to measure.
What is validity?
200
They prepare evaluative critiques of tests based on their technical and practical merits.
What are test reviewers.
200
Arithmetic average.
What is the mean.
200
Uses standards based on the performance of specific groups of people to provide information for interpreting scores.
What is norm-referenced test interpretation?
200
This results from the inclusion of items or sets of items that tap content knowledge or psychological functions that differ from those tapped by other items in the same test.
What is content heterogeniety?
200
That which we really want to know.
What is the meaning of criterion?
300
They are an important source of criteria for the evaluation of tests, testing practices and the effects of test use.
What are testing standards.
300
The flatness or peakedness of a distribution
What is kurtosis?
300
They reflect nothing more than 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 of age equivalent score scales?
300
Extension of classical test theory that uses analysis of variance (ANOVA) methods to evaluate the combined effects of multiple sources of error variance on test scores simultaneously.
What is generalizability theory.
300
This occurs when supervisors who rate job performance have access to employees' test scores.
What is criterion contamination?
400
Tests that are used in research in the fields of differential, developmental, abnormal, educational, social and vocational psychology, among others.
What is psychological research?
400
Lack of symmetry of a distribution.
What is skewness?
400
This score indicates the relative location of a score within a distribution.
What is a z score?
400
They provide confidence intervals for obtained test scores that alert test users to the fact that scores are subject to fluctuation due to measurement error.
What is standard error of measurement?
400
Its principle goals are to reduce the number of dimensions needed to describe data derived from a set of measured variables and 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 can provide.
What are factor analytic techniques.
500
The earliest antecedents of modern testing for personal selection dates back to them.
What is China BCE?
500
A mathematical procedure that allows you to predict values on one variable given information on another variable.
What is linear regression?
500
These methods apply mathematical models to test item data from large and diverse samples.
What is item response theory?
500
Method to dminister a test to a group of individuals and to create two scores for each person by splitting the test into halves.
What is split-half realibility?
500
A validation strategy that requires the collection of data on two or more distinct traits by two or more different methods.
