WGU C207 STUDY GUIDE MODULE 5
& 6 verified with correct answers
2026/2027 version
norm reference test - correct answer>>>is a test that compares an individual to other
individuals on the bell-shaped curve
criterion referenced test - correct answer>>>compares an individual to certain defined
standards
observed score - correct answer>>>is the score actually achieved by an individual on a
test.
true score - correct answer>>>is the average score an individual would achieve if he or
she were to take the test infinite times
random measurement error - correct answer>>>can eventually be eliminated over time
as the number of tests increases (according to Classic Test Theory)
systematic measurement error - correct answer>>>occurs when something that is
entirely unrelated to the test is affecting test scores
item response theory - correct answer>>>takes into account that different questions
may have different levels of difficulty
reliability index - correct answer>>>measures how well a person's observed score on a
test represents that person's true score
test retest method - correct answer>>>applies when the same test is given to the same
sample on two different occasions
parallel forms method - correct answer>>>applies when two versions of a test are given
at the same time to each of half of a sample of students
item analysis - correct answer>>>is the study of the results of each individual question
on a test
T - correct answer>>>Results-based management is built upon partnership and
inclusiveness
F - correct answer>>>Ethical issues are not a concern with the use of Big Data
, T - correct answer>>>A problem with Big Data is that there's too much of it
T - correct answer>>>Data mining will often find trends, but usually overlooks the
underlying causes
F - correct answer>>>Index numbers typically relate today's prices to those expected in
the future
F - correct answer>>>An index number of 100 indicates that the price or quantity has
increased 100 times since the base period
T - correct answer>>>The Consumer Price Index is the main measure of inflation in the
U.S.
F - correct answer>>>A ratio and a proportion are the same thing
F - correct answer>>>Prevalence and incidence are the same thing
T - correct answer>>>An incidence rate would be useful for assessing if a treatment or
preventative measure is effective in slowing the spread of a disease
F - correct answer>>>For a student who scores in the 25th percentile, this means that
only 25% scored better than this student
F - correct answer>>>Hilda scored 75 on a test with a mean of 50 and a standard
deviation of 25. On a second test she scored 60 on a test with a mean of 40 and a
standard deviation of 10. Hilda's Z-score is higher for the first test.
T - correct answer>>>Z-scores always have a mean of 0 and a standard deviation of 1
T - correct answer>>>For an ANOVA, the larger the F-ratio, the more likely there is a
statistically significant difference
T - correct answer>>>A standard score is a type of norm-referenced measurement
T - correct answer>>>The final exam for this course, in which there is a specific cut
score, is an example of a criterion-referenced test
F - correct answer>>>True Score Theory assumes that there is no random error
T - correct answer>>>The GRE and GMAT are examples where Item Response Theory
is applied to their tests
T - correct answer>>>A challenge with determining a reliability index is that it is not
possible to obtain true scores
