individuals in a population, Cognitive Domain: Knowledge, Answer Location: 5.1

Why Do Researchers Select Samples?

An accessible population is the same as a sample. Is the prior statement true or

false? Explain.

LO: 1, Ans: The statement is false. An accessible population is a portion of the

target population that can be clearly identified and from which researchers select

samples, Cognitive Domain: Comprehension, Answer Location: Selecting

samples from populations

A target population is the same as an accessible population. Is the prior statement

true or false? Explain.

LO: 1, Ans: The statement is false. An accessible population is a portion of the

larger target population that can be clearly identified, Cognitive Domain:

5. The term subject refers to animals used in research. What is the other use for this

6. 7. 8. 9. term?

LO: 2, Ans: The term subject is also used to identify the names of research

designs, Cognitive Domain: Knowledge, Answer Location: Subjects and

participants

Using probability sampling, we select sample from ______ populations, whereas

using nonprobability sampling, we select participants from ______ population.

Location: Selecting samples from populations

Which type of sampling, probability or nonprobability sampling, is used when the

likelihood of selecting each individual in a population is known and every

member of the population has an equal chance of being selected?

LO: 3, Ans: Probability sampling, Cognitive Domain: Knowledge, Answer

Location: 5.4 Methods of Sampling: Probability Sampling

Which type of nonprobability sampling uses a “first come, first serve” kind of

approach?

LO: 4, Ans: Convenience sampling, Cognitive Domain: Comprehension, Answer

Location: Convenience sampling

State two strategies researchers can use to make a convenience sample more

representative of a larger target population of interest.

LO: 4, Ans: Researchers can use quota sampling, in which they select subgroups

of the population that resemble or represent characteristics in a target population

of interest. Researchers can also use a combined sampling method, in which they

combine convenience sampling with a probability sampling method, Cognitive

Domain: Comprehension, Answer Location: Convenience sampling

10.Why would a researcher choose proportionate quota sampling method instead of

simple quota sampling?

LO: 4, Ans: A researcher would use proportionate quota sampling instead of

simple quote sampling when certain characteristics in the population are known to

be disproportionate and can be proportionately represented in a sample, Cognitive

Domain: Analysis, Answer Location: Quota sampling

11.By definition, what strategy is used with simple random sampling: sampling with

replacement or sampling without replacement?

LO: 5, Ans: Sampling with replacement. Cognitive Domain: Comprehension,

12.What sampling method involves selecting all individuals from a portion of

subgroups in a population?

LO: 5, Ans: Cluster sampling, Cognitive Domain: Knowledge, Answer Location:

Cluster sampling

13.A researcher investigates how political attitudes (Republican, Democrat) are

related to attitudes toward teaching evolution in a school classroom. To select the

sample, she is given access to a database identifying the political affiliations and

mailing addresses for all local residents in her area. She splits the list into two

subgroups (Republican, Democrat), and then selects a sample or portion of

individuals from each subgroup. To select participants from each subgroup, she

uses a random procedure to select the first address and then selects every sixth

address after that until 300 participants from each subgroup are selected. What

three sampling methods has she combined to select this sample?

LO: 5, Ans: Convenience sampling (only local residents have a chance of being

selected), simple stratified random sampling (the list is separated into subgroups,

and an equal number of participants are selected from each subgroup), and

systematic sampling (she chooses every sixth address on the list after a random

start), Cognitive Domain: Application, Answer Location: Convenience sampling,

Simple random sampling, and Systemic sampling

14.What sampling method involves randomly selecting the first participant, and then

selecting every nth person until all participants have been selected?

LO: 5, Ans: Systematic sampling, Cognitive Domain: Knowledge, Answer

Location: Systemic sampling

15.The difference between what we observe in a sample and what is true in the

population is called: [Finish the sentence]

16.State the name of the statistic used as a measure of sampling error.

LO: 6, Ans: Standard error of the mean, Cognitive Domain: Knowledge, Answer

Location: 5.5 Sampling Error and Standard Error of the Mean

17.Explain why sampling bias can lead to the selection of a sample that is not

representative of the target population.

LO: 7, Ans: Sampling bias can lead to the selection of a sample that is not

representative of the target population, but instead representative of only the

overrepresented groups in the sample due to the use of sampling proceduresPrivitera, Research Methods for the Behavioral Sciences 2e Chapter 5: Sampling From Populations

employed to favor certain individuals or groups over others, Cognitive Domain:

Analysis, Answer Location: Sampling bias

18.Explain how the nonresponse bias can limit the representativeness of a sample?

LO: 7, Ans: Nonresponse bias limit the representativeness of a sample in that

individuals in a population who respond to surveys may be systematically

different from those who do not. Hence, nonresponse bias could limit a sample to

be representative of only the portion of the population that is willing to respond to

a survey or request to participate in a study, Cognitive Domain: Analysis, Answer

Location: Nonresponse bias

19.What are participant pools for research?

LO: 8, Ans: Participant pools are accessible populations of students available and

willing to participate in research, Cognitive Domain: Knowledge, Answer

Location: Nonresponse bias

20.State two rules that ensure that participant pools are filled only with students

willing to volunteer as participants in research.

LO: 8, Ans: Class grades are never contingent on actual participation in a research

study, and students are given alternative options to receive a grade, Cognitive

Domain: Knowledge, Answer Location: Nonresponse bias
