Exam 4: Reliability

The method for estimating the internal consistency of a test that simultaneously considers all possible ways of splitting the items is the

Because classic test theory assumes a person's true score is the same over time,repeating the same test over and over gives a distribution of scores that reflect what?

If a researcher is attempting to assess the reliability of a measure of depression,the method of choice would be

The Spearman Brown formula corrects for deflated reliability due to

The standard error of measurement allows us to

What is Spearman known for?

According to classical test theory,errors of measurement are

When creating a test,one generally uses a subset of items to represent a larger construct.This is known as

The reliability of a difference score is

Upon repeated applications of the same test,performance on the second application may be affected by previous experience on the test.This is known as

The difference between David's two typing tests,one at the beginning of the semester and one at the end,reflects the fact that he typed quite a few term papers during the semester.This reflects

A split-half correlation,KR 20,and coefficient alpha are all used to evaluate

Dr.Janine developed two equivalent forms of a test and administered them both,in counter-balanced order,to a group of people on the same day in order to assess reliability.What is this called?

The work of Charles Spearman combined what two measurement concepts?

Difference scores are created by

When talking about errors in terms of psychological testing,we are referring to the fact that:

Federal government guidelines require that a test be

The kappa statistic is used to

Who developed methods for evaluating sources of error in behavioral research?

Why might different random samples of domain items yield different estimates of the true score?
