CMR exam 2 study guide questions
and answers6
simple random sample - ANSWERS -each person (or text) in the population has an equal chance
of being selected for inclusion in a study
systematic random sample - ANSWERS -in which the researcher selects the first element from a
sampling frame by chance and thereafter selects each next element systematically
stratified random sample - ANSWERS -a random selection method in which the population is
first divided into relevant subgroups so that each person or message within each subgroup has
an equal chance of being selected for the data sample
cross-sectional design - ANSWERS -a research design where a sample of data collected at one
point in time is used to draw inferences about the research question
Longitudinal study - ANSWERS -research design so that the data are collected at several points
in time
Convenience sample - ANSWERS -selection of whatever data is easily accessible to the
researcher
Purposive sample - ANSWERS -select the particular people or messages needed to test a claim
about communication within one specific context
central limit theorem - ANSWERS -large and randomly selected samples have greater chances of
approximating the true population distribution
, population - ANSWERS -the entire set of cases or instances that the researcher is attempting to
represent with a data sample.
census - ANSWERS -an official count or survey of a population, typically recording various details
of individuals
warrant - ANSWERS -standards for evaluating the worth of the data as evidence of the claim
parsimony - ANSWERS -the combination of precision and power valued in discovery research
validity - ANSWERS -Accuracy of measurement, and/or accuracy of applying conclusions from
one study to other settings, persons, or situations; a standard for evaluating discovery research
reliability - ANSWERS -consistency of measurement; a standard for evaluating discover research
power - ANSWERS -the broad scope of a definition or measurement, which is most valued in
discovery research
content validity - ANSWERS -a form of measurement validity; it is achieved when the items that
make up measuring instrument represent the full range of the behavioral domain that the
researcher is trying to measure
face validity - ANSWERS -the degree to which a measuring instrument appears to be accurate in
the view of those asked to use it, or to permit is use
test-retest method - ANSWERS -equivalence across the multiple administrations of the same
measure in the same group of subjects
