PSYCH 302- CHAPTER 7 EXAM
QUESTIONS AND ANSWERS
population - Correct Answers -entire set of people you are interested in
sample - Correct Answers -smaller set of people taken from the population
census - Correct Answers -a set of observations that contains all members of the
population of interest
biased sample - Correct Answers -A sample that does not fairly represent the
population
representative sample - Correct Answers -a sample that accurately reflects the
characteristics of the population as a whole
convenience sample - Correct Answers -only members of the population who are easily
accessible are selected
self-selection - Correct Answers -a form of sampling bias that occurs when a sample
contains only people who volunteer to participate
probability sampling - Correct Answers -A type of sampling in which every element in
the population being studied has a equal chance of being selected for study
simple random sampling - Correct Answers -the most basic form of probability sampling,
in which the sample is chosen completely at random from the population of interest
cluster sampling - Correct Answers -A probability sampling technique in which clusters
of participants within the population of interest are selected at random, followed by data
collection from all individuals in each cluster.
multistage sampling - Correct Answers -a probability sampling technique involving at
least two stages: a random sample of clusters followed by a random sample of people
within the selected clusters
stratified random sample - Correct Answers -the researcher identifies particular
demographic categories of interest and then randomly selects participants from each.
Which of the following is true regarding interrogating frequency claims? - Correct
Answers -The chief concern is to evaluate the sampling technique.
