NURS 3300 Research Final Exam Questions With
Correct Answers
Types of quantitative research - CORRECT ANSWER✔✔-descriptive, correlational,
| | | | | | | |
quasi-experimental, experimental |
ex. Likert scale, statistical analysis
| | | |
Descriptive studies - CORRECT ANSWER✔✔-Accurate portrayal or account of
| | | | | | | | |
characteristics of a particular individual, situation, or group
| | | | | | |
-Performed when collective knowledge about a phenomenon is incomplete:
| | | | | | | | |
either no research has been conducted, or there is limited research knowledge
| | | | | | | | | | |
-Purpose is to observe, describe, and document aspects of a situation (not cause
| | | | | | | | | | | | |
probing)
-Describes phenomena (ideas) in real-life situations
| | | | |
-Counts, measures, classifies the phenomena of interest or its characteristics
| | | | | | | | |
Correlational studies - CORRECT ANSWER✔✔-Systematic investigation of
| | | | | | |
relationships between or among two or more variables (an association)
| | | | | | | | |
,*Nature of relationship is NOT cause and effect*; the only way to prove this is
| | | | | | | | | | | | | | |
through quasi-experimental or experimental study
| | | |
-You can only say that there is a relationship between the two.
| | | | | | | | | | |
-Measures the numerical strength of relationships between and among variables
| | | | | | | | |
-Discovers whether a change in a value of one is likely to occur when another
| | | | | | | | | | | | | | |
increases or decreases. | |
-Changes in X do not necessarily CAUSE changes in Y (this can not be assumed
| | | | | | | | | | | | | | |
without random controlled study) | | |
-Changes in X are said to be RELATED to changes in Y.
| | | | | | | | | | |
Correlation measurement (statistic) - CORRECT ANSWER✔✔-Can be measured for
| | | | | | | |
-1 to +1
| | |
-1 is a perfect negative correlation
| | | | |
+1 is a perfect positive correlation
| | | | |
0 indicates no relationship
| | |
Can be referred to as "r" in a published report (moderative neg correlation r = -
| | | | | | | | | | | | | | |
0.53)(strong correlation r = 0.82) | | | |
Quasi-experimental studies - CORRECT ANSWER✔✔-Used to identify causal | | | | | | | |
relationships, to examine the significance of causal relationships, to clarify why
| | | | | | | | | | |
certain events happened, or for a combination of these objectives
| | | | | | | | |
, -Interventional
-Examines cause-and-effect relationships among independent and dependent
| | | | | | |
variables.
-Tests the hypothesis of a cause-and-effect relationship when an experimental
| | | | | | | | | |
design can not or should not be used.
| | | | | | |
A quasi-experiment lacks... (one of these) - CORRECT ANSWER✔✔-a researcher
| | | | | | | | | |
enacted intervention, the presence of a distinct control group, *random
| | | | | | | | | |
assignment to the group* | | |
Experimental studies - CORRECT ANSWER✔✔-Tests causal relationships with
| | | | | | | |
three criteria: (1) researcher intervention, (2) separate, distinct control group, (3)
| | | | | | | | | | |
random assignment to the group
| | | |
-Interventional
-Examines cause-and-effect relationships between independent and dependent
| | | | | | |
variables. |
-Tests the null hypothesis by means of *applying an intervention to experimental
| | | | | | | | | | | |
subjects*, but not to control subjects; and then measuring the effect on a
| | | | | | | | | | | | |
dependent variable |
Epidemiologic studies - CORRECT ANSWER✔✔-Foundation for disease control
| | | | | | | |
and prevention through tracking the prevalence of the disease, characterizing the
| | | | | | | | | |
natural history, and identifying determinants or causes of the disease.
| | | | | | | | | |
It defines risk factors for a disease and targets for preventative medicine.
