A first-year college student obtains a score of 150 on her final English exam, a score of 100 on her math exam, a score of 55 on her chemistry exam, and a score of 30 on her history exam. The means and standard deviations for these tests are, respectively, 125 and 20 for the English exam, 90 and 10 for the math exam, 45 and 5 for the chemistry exam, and 30 and 5 for the history exam. Based on this information, you can conclude that the student’s test performance was best on which exam?
Select one:
A.
English
B.
Math
C.
Chemistry
D.
History
c. chemistry
To maximize the ability of a test to discriminate among test takers, a test developer will want to include test items that vary in terms of difficulty. If the test developer wants to add more difficult items to her test, she will include items that have an item difficulty index of:
Select one:
A.
.90
B.
.50
C.
.10
D.
0
C.
.10
A final exam is developed to evaluate students’ comprehension of information presented in a high school history class. When the exam is administered to three classes of students at the end of the semester, all students obtain failing scores. This suggests that the exam may have poor ________ validity.
Select one:
A.
concurrent
B.
incremental
C.
content
D.
divergent
C.
content
The correction for attenuation formula is used to measure the impact of increasing:
Select one:
A.
a test’s reliability on its validity
B.
a test’s validity on its reliability
C.
the number of test items on the test’s validity
D.
the number of test items on the test’s reliability
A.
a test’s reliability on its validity
When a test has been constructed on the basis of item response theory, an examinee’s total test score provides information about his/her:
Select one:
A.
status on a latent trait or ability
B.
predicted performance on an external criterion
C.
performance relative to other examinees included in the standardization sample
D.
current developmental level
A.
status on a latent trait or ability
The primary advantage in using a percentile rank, z-score, or T-score is that these scores:
Select one:
A.
are easy to interpret because they reference an individual’s test performance to an established standard of performance
B.
are easy to interpret because they reference an individual’s test performance to the performance of other examinees
C.
are easy to interpret because they make it possible to predict which criterion group an examinee is likely to belong to
D.
normalize the raw score distribution so that parametric tests can be used to analyze test scores
B.
are easy to interpret because they reference an individual’s test performance to the performance of other examinees
You would use a multitrait-multimethod matrix in order to:
Select one:
A.
compare a test’s predictive and concurrent validity
B.
determine if a test has adequate convergent and discriminant validity
C.
identify the common factors underlying a set of related constructs
D.
test hypotheses about the causal relationships among variables
B.
determine if a test has adequate convergent and discriminant validity
