C431 WGU Quiz 1 and Answers
When the subjects in a study sampling bias
are not representative of the
population, this is a limitation
referred to as ___.
___ is when the determination of publication bias
whether to publish a study is
based on factors other than the
quality of the research and the
relevance of its findings.
observational study that is large in Cohort study
size and longitudinal in duration.
The groups in the study are
determined by a given exposure,
characteristic, or risk factor.
prospective study in which Cross-over study
patients are moved from one
group to another. They are in the
control group for a period of
time and then be moved to
one or more treatment groups.
Subjects remain in each group
long enough to determine the
effect of the given treatment.
___ a research procedure in which all Systematic review
prior studies on a given topic
are brought together and
analyzed collectively.
study in which the allocation of Randomized control trial
patients to treatment or control
groups is random and concealed.
At least one control group must
be utilized. Preferably patients,
as well as providers, are not
informed (blinded) regarding
which intervention patients
receive.
, Researchers strive to remain Objectivity
unbiased, honest, and precise
when making decisions regarding
the planning, conducting, and
reporting of a quantitative and
qualitative study. The previous
statement defines
Identify the characteristic of External validity
research design that relates to
the degree to which the
outcomes of the study can be
attributed to the interventions.
What variables interfere with the Extraneous
intended purpose of the variable
investigation by introducing error Intervening
to the study? variable
What is the procedure called for External validity
assigning subjects to
intervention groups (placebo
group, control group,
experimental group.
Identify the type of evidence that Meta-analysis
combines the statistically
analyses of multiple
independently conducted
studies.
Ensure the sample size was large enough to detect differences in the
A power analysis is calculated to
treatment and comparison group after data collection
In a statistical power effect size
calculation, it is the expected
amount of effect that is
considered a minimal clinically
meaningful difference.
The range in which the true confidence interval
parameter can be found, within
a given percentage likelihood.
The probability of a Type I alpha
error, selected during the
design of the research. It
represents the researchers'
risk of incorrectly rejecting the
null hypothesis (of saying there
is a difference when in fact
there is not).
The value produced by a statistical test statistic
test.
