Exam 5: Selecting Research Participants

Quota sampling produces the same advantages for convenience sampling that ____ sampling produces for probability sampling.

The accessible population is a subset of the target population.

Stratified random sampling is used instead of simple random sampling when a researcher wants to ensure that the subgroups within a population are represented in the sample.

One advantage of simple random sampling with replacement is that the likelihood of selecting one specific individual does not depend on which other individuals are selected for the sample.

One criticism of a stratified random sample is that ____.

A researcher would like to select a sample of 50 people so that five different age groups are equally represented in the sample. Assuming that the researcher does not know the entire list of people in the population, which sampling technique should be used?

Which sampling technique is most likely to result in a biased sample?

What is a concern with simple random sampling without replacement?

When a sample has the same characteristics as the target population, the sample is said to be a(n) ____ sample.

To select a sample of 10 employees from a factory workforce of 100, a researcher puts each employee's name on a slip of paper, then shuffles the papers in a hat and randomly picks 10 names. What kind of sampling is being used?

When a researcher does not know the exact number of individuals in the population but still wants to control the composition of a sample, the best technique is to use quota sampling.

When the goal of a research study is to describe and compare different subgroups in a known population, the best strategy is to use proportionate stratified random sampling.

The group of individuals from which researchers actually select participants for research studies is called the ____ population.

Although a research question usually concerns the ____, the actual research participants are selected from the ____.

A teacher obtains a sample of children from a fifth-grade classroom by randomly selecting the third, fifth, and eighth rows and taking all the students in those rows. This is an example of ____ sampling.

Which kind of sampling requires such extensive knowledge of the population that the researcher could list every individual in the population?

A sample consists of 25 freshmen, 25 sophomores, 25 juniors, and 25 seniors from a local high school that has an equal number of students in each class. If the sample was obtained using a list of all the students in the high school, it is probably an example of ____ sampling. If the sample was obtained without a list of students, it is likely an example of ____ sampling.

Stratified and proportionate stratified sampling both involve selecting individuals from predetermined subgroups in the population.

If you cannot list all the individuals in the population, then you cannot take a simple random sample.

There is a strong possibility that a convenience sample will be biased.
