Sampling methods
This quantitative study design uses a probability sampling method.
What is a true experimental study design?
This quantitative study design's sampling method can be expensive and time consuming if done correctly.
What are true experimental studies?
This study design aims to establish causality.
What are true experimental studies?
In a small RN-to-BSN program, does playing jeopardy increase knowledge and understanding of quantitative research designs?
(Hint: independent variable is jeopardy game)
Pre-experimental design:
One group posttest only
One-group pre-test post-test
This type of validity is the degree to which the results of the study can be generalized to other subjects, settings, and time.
What is external validity?
This type of sampling method is commonly used in qualitative research designs.
What is non-probability purposive sampling?
This quantitative study design cannot make strong claims of cause and effect due to lack of randomization or a control group.
What are quasi-experimental designs?
This broad category of epidemiological studies can be used to measure the prevalence of exposure and disease.
What are descriptive epidemiological studies?
How many current cases (prevalence) of COVID-19 are there in King Co. today?
This type of validity is the degree to which the instrument or empirical indicator actually measure the theoretical concept of interest.
What is construct validity?
This type of sampling method has the highest risk for bias.
What is convenience sampling?
This epidemiological type of study aggregates data based on individual-level data, which may be falsely assumed/inferred to be true for populations.
What are ecologic studies?
"Ecologic fallacy"
This specific epidemiological study type includes participants based on whether or not they have a disease. Due to this, this study type is less prone to loss to follow-up (or high attrition/drop-out rates) because it is a retrospective study.
What is a case-control study?
What diet and lifestyle risk factors are associated with colon cancer?
What are analytic epidemiological studies (cohort studies)?
Chronbach's α measures this in a tool.
What is internal consistency or homogeneity of measure?
Also acceptable:
Consistency of measurement
reliability
This type of randomization strengthens internal validity.
What is random assignment?
This specific type of non-experimental quantitative study aims to understand if/how variables are associated with each other based on a theory. Limitation: they can only provide a SUGGESTION of causality.
What are correlational designs?
This specific type of true experimental design seeks to investigate if the specific tool/instrument used to test changes in the dependent variable influences the outcome.
What is Solomon-Four Group design?
Among construction workers diagnosed with mesothelioma, how many were exposed to asbestos?
What is an analytic epidemiological design (case-control study)?
Researchers use test-retest to measure this in a tool.
What is stability of measure?
Also acceptable: reliability
This type of sampling strengthens external validity.
What is random sampling?
Nonequivalent control group designs have a comparison group but threats of internal validity exist due to this sampling method.
What is a non-probability sampling method?
This study type involves more than one intervention and can compare multiple interventions or multiple levels of interventions.
What are factorial designs? (True experimental study)
Do nurses who exercise after working night shift have improved sleep quality?
What is a correlational design (predictive correlational study)?
This type of validity has more to do with design than measurement.
What is external validity?
What is internal validity?
What is statistical conclusion validity?
