28.5/30
CEFS 521 Quiz 3, Liberty University
QUESTION 1 1.5 points
The researcher reports the standard error of measurement (SEM). This is:
a different term for the standard deviation
the spread of scores of a single individual if he/she took a test repeated times
the spread of scores of a group of test takers on a single test
a measure to use alone as an index of reliability
1.5 points
QUESTION 2
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 3
If the reliability coefficient of a test is determined to be .27, what percentage is attributed
to random chance or error?
27%
73%
2.7%
unknown percentage
1.5 points
QUESTION 4
Several test takers complained that items on the test were vague and confusing. This
creates concern for:
time-sampling error
, 28.5/30
interrater differences
quality of test items
test-taker variables
1.5 points
QUESTION 5
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:
test does not have dichotomous test items
researcher needs a second test for comparison
test does not measure internal consistency reliability
researcher is concerned with content sampling error
1.5 points
QUESTION 6
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
QUESTION 7
A test was administered to a group of students the morning after homecoming. Several
of the students appeared tired and some were coughing and sneezing. These factors
may result in what type of error:
time-sampling error
test administration
quality of test items
test-taker variables
1.5 points
QUESTION 8
Keisha receives a 79 on the test. This is her:
true score
reported score
observed
score
