It's Valid and Reliable and Ethical
In a randomized interview study on workplace dynamics, this ensures that findings apply to other organizations with similar conditions.
What is external validity?
Convenient sampling, snowball sampling, and purposive sampling are all examples of what kind of sampling?
What is nonprobability sampling?
This sampling method is used when you want to separate your sample into a few relevant categories to ensure you have sufficient respondents in each category.
What is stratified random sampling?
This method involves an open-ended conversation between researcher and participant that goes from broad to specific.
What is a semi-structured interview?
This form of validity is very strong for experiments.
What is internal validity?
This type of validity ensures that the results of an experiment are truly due to the independent variable and not spuriousness.
What is internal validity?
In qualitative research, this sampling technique involves selecting participants who refer the researcher to additional participants, typically aiming for depth rather than broad generalization.
What is snowball sampling?
The best sampling method if you want to generalize your findings to a broad population without a complex design.
What is simple random sampling?
This method produces rich, detailed descriptions of a social process.
What is ethnography/(non)participant observation?
This survey question asks about two different things in one question.
What is a double barreled question?
In a survey study about job satisfaction, this ensures that employees would give consistent responses to the same questions if the survey were repeated a week later under identical conditions.
What is reliability?
This nonprobability method selects participants based on their accessibility and availability to the researcher.
what is convenience sampling?
A researcher decides to interview every 8th apartment door in a new housing development. This is what kind of sampling?
What is systematic random sampling?
This is how ethnographers organize their data at the end of each observation day.
What are field notes?
This type of experiment is done in the real world, not in a lab.
What is a field experiment?
This type of validity refers to how well a test or instrument measures the concept it is intended to measure.
what is construct validity?
Nonprobability sampling is low in this type of validity.
What is external validity?
A public health researcher wants to study vaccination rates. First, they divide the population based on counties and randomly select a few counties. Within each selected county, they select individuals by age groups (e.g., children, adults, seniors) and randomly sample participants from each age group to ensure representation.
What is this sampling strategy called?
What is stratified random sampling?
A term for follow-up questions in your interview guide.
What is a probe?
“Do you think abortion is murder?” is an example of this type of survey question.
What is a loaded question?
This control substance, often used in clinical trials and experiments, raises ethical concerns if participants are later denied access to proven treatments.
what is a placebo?
This type of non-probability sampling captures a wide range of perspectives and conditions.
What is maximum variation sampling?
Sampling with this method involves selecting institutions proportional to their size and sampling all people with selected institutions.
What is cluster random sampling?
A term for when your field work/interviews aren’t yielding new information, and you can conclude observations/interviews.
What is saturation?
These are done before and after the treatment is administered.
What are pre-testing and post-testing?
