Nursing Research Exam 2 ECPI
College Questions and Answers5
Operational Definition - ANSWERS-explanation of the procedures that must be performed to
accurately represent the concepts
Descriptive Research Study - ANSWERS-research designed to describe in detail some process,
event, or outcome. Such a design is used when very little is known about the research question.
Confirmation of causality - ANSWERS-the better job the researcher does in extracting anything
that would compromise the study, the better the study will be and the more the nurse can apply
the study to practice confidently.
Temporality - ANSWERS-the time sequence between the independent and dependent variables
must support causation.
Influence - ANSWERS-the effect that the independent variable has on the dependent variable
can be detected statistically, and the probability that the relationship was caused by chance is
small
Specificity - ANSWERS-rival explanations for the specific relationship between the independent
variable and dependent variable have been eliminated or destroyed
Possible cause - ANSWERS-there is an association and a correlation, but we cannot determine
whether the correlation implies causality
Probable cause - ANSWERS-suspect that the correlation involves cause
, Cause beyond reasonable doubt - ANSWERS-we have a replicable model that successfully
explains how one thing causes another
Descriptive variable - ANSWERS-characteristics that describe the sample and provide a
composite picture of the subjects of the study; they are not manipulated or controlled by the
researcher
Primary data - ANSWERS-data collected directly from the subject for the purpose for the
research study
Secondary data - ANSWERS-data collected for other purposes and used in the research study.
Reliability - ANSWERS-consistency
Validity - ANSWERS-Accuracy
Probability sampling (Random Sampling) - ANSWERS-refers to a sampling process in which every
member of the available population has an equal probability of being selected for the sample
Simple random sampling - ANSWERS-when a table of numbers is used to select subjects form
the sampling frame
Systematic random sampling - ANSWERS-first subject is drawn randomly, and remaining subjects
are selected at predetermined intervals
Stratified random sampling - ANSWERS-so structured that important characteristics are evenly
distributed across all groups.
