Exam 5: Sampling and Generalizability

To conduct a survey on current political science majors, a researcher gets a list of all students who have declared a political science major from the registrar from which a sample will be drawn. This list is known as what?

The population is the entire set of individuals or other entities to which study findings are to be generalized.

What is the probability of selection for any man in a proportionate random sample, where a sample of 100 will be drawn from a population of 1,000 that is 50% male and 50% female?

If anything other than chance determines which elements are selected for the sample, the sample is said to have:

When all elements in a population are identical:

In purposive sampling, interviews should continue until a saturation point is reached.

A researcher is working with data collected through responses from or about the available members of the entire population of the United States, also known as:

Cluster sampling is a type of sampling in which elements are selected in two or more states, with the first stage being random selection of naturally occurring clusters.

In a census, the probability of selection for all elements is:

In what circumstances is a simple random sample possible? Describe at least four techniques can be used in drawing a simple random sample. How does this contrast with drawing a systematic random sample? In what situations is a systematic random sample as good as a simple random sample, and in what situations is it clearly worse?

In social research, what is the importance of sampling? Why are probability sampling techniques superior to non-probability sampling in achieving this end?

Another name for convenience sampling is:

In what circumstances are non-probability sampling methods appropriate? What are the limitations of using non-probability sampling methods?

You have been hired by the Department of Institutional Research to find out if students at State University work while they're in school. You have access to the complete list of students registered this semester. Design a stratified random sample and a quota sample of students at State University, where the student population has the following salient characteristics: 50% male, 50% female; 75% white, not Hispanic, 25% racial or ethnic minority. Discuss the different procedures for each and explain the advantages and disadvantages of each.

Purposive sampling selects elements for inclusion in the sample based on chance.

The individual members of the population whose characteristics are to be measured are known as:

A subset of the population used to study the population as a whole is known as a(n):

It is not possible to determine the probability of selection of elements in a disproportionate stratified random sample.

Availability sampling is another name for simple random sampling.
