What is experimental method
A researcher is concerned with whether or not a studies results are generalizable to a similar group or to the population.

D) Double blind Study.
What is C
What three important characteristics are associated with conducting experimental designs
1. Control
2. Random Assignment
3. Manipulation
4. Differences

Double blind study
Correlational study
Pretest posttest study
quasi-experimental study
What is correlational research?
TRIPLE SCORE
A researcher understands that the most widely accepted approach to evaluating the effectiveness of an interventions or a treatment in a sample is what type of study
Random Control trial
Single blind study
qualitative study
Randomized posttest only trial
What is a randomized control trial
A researcher wanting to ensure that a study's sample has an equal opportunity to be in the experimental group as in the control group should use _____________.
pretest posttest
random assignment
manipulation of the population
Control of components of the design
What is random assignment?
In this type of design, only the participants are unaware of the hypothesis of the study and to which group they are assigned.
Double blind study
single blind randomized control study
non experimental study
qualitative study design
What is single-blinded randomized control study (RTC) ?
A researcher designs a study when research participants all receive the treatment and then experience a period of time that they do not receive the treatment.
Qualitative design
Quasi-experimental design
descriptive design
Double Blind Study design
What is quasi-experimental lacking control?
An inpatient acute rehabilitation facility collects information on one patient with Parkinson's disease over a period of 3 weeks.
Case Study research
experimental research
quasi-experimental research
Correlational research
What is quantitative case study research?
What type of validity refers to whether the independent variable made a difference in the study?
What is Internal validity.
DAILY DOUBLE
A researcher attempts to eliminate any irrelevant influences on a study's design.
random assignment
manipulation
control
variables
What is control?
DAILY DOUBLE
What type of research design is appropriate looking to combine the results of many research studies in a specific area and synthesizes their findings to draw conclusions?
1. factorial design
2. meta analysis
3. epidemiological research
4. analytic study
What is a Meta analysis
This type of research design is MOST APPROPRIATE when a researcher wants to study naturally occurring situations or it is unethical to use a control group.
Meta-analysis
Internal Validity
Quasi-experimental
Randomized Control trial
What is quasi-experimental?
Studies in which the dependent variable has already occurred, for example a disease or disability are considered _______________
retrospective
prospective
introspective
ultraspective
What is retrospective?
_______________ validity is the degree to which your research measures the construct (as compared to things outside the construct).
What is an construct validity?
DAILY DOUBLE
What is the variable that researchers try to manipulate?
What is independent variable
What type of research design does this notion indicate?
R O X O
1. pretest posttest control group design
2. Posttest only control group design
3. one group pretest posttest design
What is pre-test - post-test control group design
Following the identification of a researchable problem, what must the nurse do?
A) Obtain a list of possible outcomes.
B) Evaluate the number of ways to collect data
C) Select literature relevant to the problem.
D) Determine a source appropriate to collect data.
What is Ans: C
Feedback:
Literature review is the process of selecting published materials that have relevance to the potential research.
An OTR sent out a questionaire to individuals with rheumatoid arthritis (RA) to determine the impact of RA on quality of life.
historical research
qualitative research
survey research
meta analysis
What is survey research?
TRIPLE SCORE
A _______________ research design investigates relationships between two variables (or more) without the researcher controlling or manipulating any of them.
What is a correlational research design
Nursing research is linked most closely to:
A) propositions.
B) outcome measures.
C) treatments.
D) nursing process.
Ans: D
Feedback:
Many similarities are found between the formalized research process and the nursing process format that is an integral part of nursing education.
