CEFS 521 Quiz 3, Liberty University
QUESTION 1
1. When interviewing test takers who had an achievement test on three different
occasions, participants reported that they had remembered some of the answers from
the previous test administration. This is known as:
practice effect
content effect
test-retest effect
carryover effect
1.5 points
QUESTION 2
1. The test manual reports a reliability coefficient (r) of .92, which means:
92% of the variance in scores is attributed to error
92% of the variance in scores is explained by real differences
nothing conclusively because it depends on the method used
nothing conclusively because it depends on the source of measurement
error
1.5 points
QUESTION 3
1. Keisha receives a 79 on the test. This is her:
true score
reported score
observed
score
predicted
score
1.5 points
, QUESTION 4
1. You are reading about reliability of a test in the test manual and notice that the
researchers report using a Spearman-Brown coefficient. You can infer that internal
consistency reliability was measured using:
the Kuder-Richardson formulas
coefficient alpha
split-half reliability
test-retest
1.5 points
QUESTION 5
1. 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?
Split-half reliability
The Kuder-Richardson formulas
Coefficient alpha
Any of the above methods would be equally appropriate
1.5 points
QUESTION 6
1. You are attempting to account for time sampling error and decide to administer the test
a second time.In discussing reliability, you report this as what method of estimating
reliability?
Alternate forms
Test-retest
Split-half reliability
Internal consistency reliability
1.5 points
QUESTION 7
1. A researcher wants to measure content-sampling error with a Likert scale test. Which of
the following methods would be best?
Test-retest
Coefficient Alpha
The Kuder-Richardson
formulas
Interrater differences
1.5 points
