WGU C207 STUDY GUIDE MODULE 5 & 6
UPDATED ACTUAL Exam Questions and
CORRECT Answers
incidence rate - CORRECT ANSWER would be used if we want to measure the proportion of
health workers who acquire Ebola from working with Ebola patients
percentile - CORRECT ANSWER indicates the percent of the population that falls below a
certain value
standard score - CORRECT ANSWER for a particular data point, represents the distance from
the mean in terms of standard deviations
Analysis of variance (ANOVA) - CORRECT ANSWER is used to determine if three or more
sample means are statistically not all equal
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
