ACTUAL QUESTIONS AND CORRECT ANSWERS
Question:
what is a population?
Answer:
a well defined set that has certain specified characteristics from which data are
collected and analyzed
Question:
_________ and _________ criteria lead to sample selection
Answer:
inclusion (eligibility) exclusion (deliminations)
Question:
what is homogeneity in a sample?
Answer:
similar, limited variation in characteristics
Question:
what is heterogeneity in a sample?
Answer:
diverse, dissimilarities
Question:
why is heterogeneity in a sample bad?
Answer:
it inhibits the ability to interpret findings meaningfully and to make generalizations
Question:
___________ establishes the target population
Answer:
population criteria
Question:
what is the accessible population?
Answer:
the population that meets the study eligibility criteria and is available
Question:
what is sampling?
Answer:
the process of selecting a subset of the population to represent the entire population
, Question:
what is a sample?
Answer:
a set of elements that make up the population
Question:
what is an element?
Answer:
the most basic unit about which information is collected
Question:
what is the goal of sampling?
Answer:
to make inferences about a population from what we know about our sample to be able
to generalize findings about a population
Question:
what is representativeness?
Answer:
how close the sample is to the characteristics of the population it was selected from
Question:
we can best ensure representativeness by using a _________________ approach, having
clear _______________, and having a ___________________ sample
Answer:
probability sampling approach eligibility criteria large enough sample
Question:
what are the two sampling strategies?
Answer:
nonprobability sampling probability sampling
Question:
what is nonprobability sampling?
Answer:
participants are selected using non-random methods
Question:
what is probability sampling?
Answer:
uses random methods for selecting samples
Question:
what are the two types of nonprobability sampling? what do they mean?
Answer:
convenience - the most readily accessible population quota - knowledge about the
population is used to seek representativeness by using strata
