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

Extreme-case sampling and maximum variation sampling are more likely to be used in what kind of research?

Which of the following are not likely to be true of a study using opportunistic sampling?

Disproportionate stratified random sampling:

You can create a stratified sample by dividing the population into mutually exclusive groups and then choosing a random sample from each group.

List and explain the characteristics of the different nonrandom sampling techniques.

Which of the following statements is true?

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

In two-stage cluster sampling, random selection is done:

Carly drew a sample by first identifying a comprehensive set of subgroups based on one or more variables, and then individuals were randomly selected from each of those subgroups. Carly used the technique known as:

Describe equal probability of selection methods of sampling and give examples of equal probability of selection methods.

A research team is conducting a national study of the percentage of household income that is spent on health care. Using national data, they divide the population based on household income data. In this example, household income is a:

Proportional stratified sampling is preferred when the researcher's goal is to compare groups.

In comparison to simple random sampling, proportional stratified random sampling tends to be:

Snowball sampling occurs when:

When using a random number generator, you will occasionally get strings of non-random numbers and should discard those numbers and move on to other numbers.

An environmental action group is interested in how many people will participate in a recycling program in a particular town. They obtain the entire list of households in the town, and they assign each household a number from 1 to 3000 (the number of households in the town). They then use a computer to generate a list of 500 random numbers ranging from 1 to 3000. Using the list of random numbers, they draw a sample of 500 people to question about their use of the recycling program. What sampling method did this group use?

A type of sampling in which the researcher determines the appropriate sample sizes for the groups identified as important and takes convenience samples from those groups.

Which of the following is an equal probability of selection method of sampling?

List the factors that you should consider when determining the appropriate sample size to be selected when using random sampling.

Know which sampling techniques are equal probability of selection methods.
