ETHICS
True
Eye color is an example of which type of level of measurement?
Nominal
This variable is the focus of the research and represents the outcome of interest.
Dependent variable
List the 4 types of probability sampling that we have covered.
simple random sampling, systematic, stratified, cluster
Simple random sampling is a type of nonprobability sampling. (T or F).
Children are considered to be a vulnerable population according to the IRB. (T or F)
True
SAT scores are an example of which type of level of measurement?
Interval
Independent variable
Writing everyone's name down on a piece of paper, putting them in a hat, and then selecting pieces of paper until you achieve your desired sample size is an example of which type of sampling?
simple random sampling
Stopping the first 10 people you run into and surveying them is an example of which type of sampling?
Convenience (or "accidental" "haphazard")
What are the 3 types of IRB review categories?
Exempt, expedited, full board (i.e., full panel review)
Number of arrests made on a given day is an example of which type of level of measurement?
Ratio
This type of variable is included in research to better isolate the role of an IV on the DV.
Control variable
Which probability sampling approach requires you to calculate a sampling interval to select every "nth" item in a list to be included in a sample?
Systematic sampling
Which sampling approach is based on referrals from participants?
Snowball (or "network sampling" "chain referral sampling" "reputational sampling")
Which Belmont Report principle states that individuals should be treated as autonomous agents and autonomy must be acknowledged?
Respect for persons
Which two levels of measurement have equal intervals or distances between categories?
Interval and ratio
RQ: "does age predict misconduct rates?"
what is the IV?
age
This type of sampling divides a population into subgroups (based on a similar characteristic that form "strata") and randomly selects within each stratum.
Stratified random sampling
Which type of sampling requires the researcher to use their expertise and judgment to select individuals for the sample?
Judgmental / Purposive sampling
Which Belmont Report requirement requires voluntary participation after all sufficient information is provided and is comprehensible to the participant?
Informed consent
Interval has a meaningful zero, whereas ratio does not have a meaningful zero. (T or F).
False
RQ: "does program participation predict recidivism?"
What is the DV?
recidivism
what is the formula used to determine the sampling interval in systematic sampling?
k = N / n
(k= sampling interval; N=population size; n=desired sample size)
Nonprobability sampling is more likely to generate representative and generalizable samples. (T or F)
False
