Nursing Research Module 5
1. What is a research design?
Strategy that researchers use to answer their research questions and hypotheses
2. What does a p value mean? What does it means if your p value is < .05? p< .001?
P value is the calculated probability. If the p value is less than 0.5 the study was statistically significant
and there is a 95% chance that the same results would occur if the study was done again.
3. What are the three characteristics associated with an experimental design (study)?
Manipulation, randomization, control
4. What is the difference between experimental and non-experimental designs?
-Experimental - Randomized, Controlled, Trial (RCT). Characterized by manipulation, randomization, and
control
-non-experimental - Tests the association between two or more variables, A phenomena observed in the
present is linked with phenomena that occurred in the past. This is a type of correlational study
5. What is the difference between an experimental and a control group?
Experimental receives the treatment whereas control group doesn't
6. What are the advantages and disadvantages of doing experimental research?
Advantages - best for testing cause and effect relationships
Disadvantages - many variables can't be manipulated, other variables cannot be ethically manipulated,
impracticality
