Exam 10: Sampling in Quantitative, Qualitative, and Mixed Research

A table of random numbers or a random number generator should be used when:

The response rate is the "number of people in the original sample who participate" divided by the "total number of people in the original sample."

Define the key terms used in sampling (representative sample, generalize, element, statistic, parameter, and so forth).

A researcher asked each study participant to identify two other potential participants. This is an example of snowball sampling.

Simple random sampling is more efficient than proportional stratified sampling.

Sampling procedures are the same for quantitative and qualitative research.

A researcher is interested in studying a nationwide representative sample of the United States. She randomly chooses places to study using census tracts. She then randomly samples within each census tract from among the households within those tracts. What sampling method did this researcher use?

"Probability proportional to size" means:

Which of the following techniques yields a simple random sample?

When looking at a fairly homogeneous population, the sample size required is usually ________ than the sample size needed in a fairly heterogeneous one.

Compare and contrast the different random sampling techniques.

Systematic sampling yields a representative sample when:

Discuss sampling in qualitative research and compare and contrast the different sampling techniques used in qualitative research.

A sample that is systematically different from the population is called:

In two-stage cluster sampling, random selection occurs at both stages.

Paul is conducting a mixed research study. He will interact with the participants on two occasions. During the first interaction, participants will complete a questionnaire. During the second, Paul will interview them about the topic he is studying. This study uses:

In comparison to national statistics, the sample in a researcher's study was composed of twice as many Hispanic students as in the population. This sample is considered to be a:

The purposes of sampling differ in quantitative and qualitative studies. Describe the different purposes of sampling in quantitative and qualitative research studies.

When elements are not allowed to be selected more than once, this is called:

Determining the sample interval (represented by k), randomly selecting a number between 1 and k, and then including every k^th element in your sample are the steps for which type of sampling?
