1.25 / 1.25 pts
Question 1
A researcher wants to measure content-sampling
error and has two versions of an achievement test
available. What measure of estimating reliability
would be best in this situation?
Alternate forms Test-retest Split-Half reliability Internal consistency reliability 1.25 / 1.25 pts
Question 2
Jose has developed a test that has poor reliability;
he can seek to increase reliability by:
Increasing the number of test questions. Decreasing the number of test questions. Making the test questions more ambiguous. Starting over and developing a new test. 1.25 / 1.25 pts
Question 3
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 Kuder-Richardson Formulas CoeRcient alpha Any of the above methods would be equally
appropriate.
1.25 / 1.25 pts
Question 4
If the reliability coeRcient of a test is determined to
be .27, what percentage is attributed to random
chance or error?
27% 73% 2.7% Unknown percentage 1.25 / 1.25 pts
Question 5
You are attempting to account for a 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 1.25 / 1.25 pts
Question 6
In reviewing a newly developed test instrument, the
evaluator noticed that some of the items did not
appear to reWect the construct being measured; he
reported there was:
Content-sampling error Time-sampling error Interrater differences error Test-taker variables error 1.25 / 1.25 pts
Question 7
An administrator and the school psychologist were
observing a child to assess for behavioral problems.
An error may occur in reviewing what the two
observers notice; this is reported as:
Content-sampling error Time-sampling error Interrater differences Test-taker variables 1.25 / 1.25 pts
Question 8
You are reading about reliability of a test in the test
manual and notice that the researchers report using
a Spearman-Brown coeRcient. You can infer that
internal consistency reliability was measured using:
The Kuder-Richardson Formulas CoeRcient alpha Split-half reliability Test-retest 1.25 / 1.25 pts
Question 9
When interviewing test takers who had taken 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 1.25 / 1.25 pts
Question 10
The SEM for an achievement test is 2.45. Johnny
scores 100 and we assume that 68% of the time his
true score falls between + 1 SEM; this means the
con\dence interval would be between:
0 and 102.45 2.45 and 100 95.10 and 104.90 97.55 and 102.45 1.25 / 1.25 pts
Question 11
_______________ is calculated by correlating test
scores with the scores of tests or measures that
assess the same construct.
Convergent validity Discriminant validity Face validity Content validity 1.25 / 1.25 pts
Question 12
A professor wants to assess students’ knowledge of
material taught through lectures. However, the
professor asks questions that were not discussed
during class lectures. This may result in problems
with _______________ validity.
Construct Content Discriminate Face 1.25 / 1.25 pts
Question 13
Comparing pre and post-test scores of two groups –
one group that experienced an intervention and one
group that did not – is an example of:
Factor analysis. Contrasted group studies. Experimental results. Age differentiation studies. 1.25 / 1.25 pts
Question 14
Convergent validity evidence is established by
___________
correlating instrument results with the results of
other instruments that assess the same construct
correlating results among four or more
instruments
having experts determine whether a test measures
the same construct
factor matrix 1.25 / 1.25 pts
Question 15
A test designed for elementary school children was
administered to 11th grade students. To these
students, the test seemed extremely childish and
inappropriate. They cooperated poorly with the
testing procedure, and, as a result, this negatively
impacted their outcomes on the test. Which of the
following would have best addressed this problem?
Evidence of homogeneity. Discriminant evidence. Evidence based on consequences of testing. Evidence based on response processes. 1.25 / 1.25 pts
Question 16
The tripartite view of validity includes content
validity, criterion validity, and:
Discriminate validity Convergent validity Content validity Construct validity 1.25 / 1.25 pts
Question 17
Exploratory factor analysis can be used to:
Investigate the differences between groups. Develop new testing instruments. Con\rm expectations about a scale's dimensions.
Determine if a test produces negative
consequences.
1.25 / 1.25 pts
Question 18
_______________ is a threat to validity that implies that
a test is too narrow and fails to include important
dimensions or aspects of the identi\ed construct.
Content underrepresentation Content-irrelevant variance Construct underrepresentation Construct-irrelevant variance 1.25 / 1.25 pts
Question 19
Validity coeRcients greater than __________ are
considered in the very high range.
.50 .60 .70 .80 1.25 / 1.25 pts

To evaluate a content validity evidence, test
developers may use:
Expert judges Factor analysis Experimental results Evidence of homogeneity Quiz Score: 25

Question with last attempt is displayed for your review only
Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the
overall stock market. On January 31, 2006, 9 of the 30 stocks making up the DJIA increased in price (The Wall Street
Journal, February 1, 2006). On the basis of this fact, a financial analyst claims we can assume that 30% of the stocks
traded on the New York Stock Exchange (NYSE) went up the same day
A sample of 61 stocks traded on the NYSE that day showed that 29 went up.
You are conducting a study to see if the proportion of stocks that went up is is significantly more than 03. You use a
significance level of a 0.001.

decimal places.)
