CEFS 521 Quiz 3
Question 1
1.5 out of 1.5 points
A researcher administers an achievement test to the same group of
participants on three different occasions. In reporting the results, he
describes the error that occurs from repeatedly testing the same
individuals. This is called:
Selected Answer: time-sampling error
Question 2
1.5 out of 1.5 points
When the researcher interprets the reliability coefficient, the closer the
score is to 0,:
Selected Answer: the more the scores represent random error
Question 3
1.5 out of 1.5 points
The test manual reports a reliability coefficient (r) of .92, which
means:
Selected 92% of the variance in scores is explained by real
Answer: differences
Question 4
, 1.5 out of 1.5 points
Several test takers complained that items on the test were vague and
confusing. This creates concern for:
Selected Answer: quality of test items
Question 5
0 out of 1.5 points
A researcher wants to measure internal consistency in a test that
measures two different constructs (self-esteem and depression) without
subdividing the items into the two construct groupings. Which of the
following would be the best method to use in measuring internal
consistency?
Selected Any of the above methods would be equally
Answer: appropriate
Question 6
1.5 out of 1.5 points
A researcher is concerned with measuring internal consistency
reliability and has decided to use the Kuder- Richardson Formulas with
a Likert Scale test. This is a problem because the:
Selected Answer: test does not have dichotomous test items
Question 7
1.5 out of 1.5 points
Jose has developed a test that has poor reliability. He can seek to
increase reliability by:
Selected Answer: increasing the number of test questions
