Exam 7: Sampling Approaches and Considerations

Calvin has defined the target population of a study to be human resource managers in small manufacturing firms (i.e., under $1 million in sales). He wants to collect data from all members of the target population. Calvin wants to collect a _____.

Which type of sampling involved selecting initial respondents typically using probability methods but then have them help identify other respondents in the target population?

Which type of sampling method assigns each element of the target population an equal probability of being selected?

If a population is made up of homogeneous groups, such as ethnic groups, which type of sampling method is appropriate?

June wants to collect a sample based on the premise that each element of the target population has a known, but not necessarily equal, probability of being selected. She wants a sample that is representative of the target population. June should use a _____ method to select her sample.

Which type of sample involves selecting elements in the sample bases on the researcher deciding which elements should be included in the sample?

Systematic sampling is a process that involves randomly selecting an initial starting point on a list and thereafter every nth element from the sampling frame is selected.

A researcher has been commissioned to examine why employee turnover is so high in a company. After determining that most of the turnover is among employees in the Southeast, the researcher defined those employees as the target population. Once the target population has been defined by the researcher, what is the next step in the sampling process?

A sample is not a reasonably large portion of the population.

All of the following are ways in which a sampling frame is flawed EXCEPT _____.

Quota sampling is not similar to stratified random sampling.

In _____ sampling, the selection of elements for the sample is not necessarily made with the aim of being statistically representative of the population. Thus, not every element in the population has a chance of being selected into the sample and the error associated with the sample is not known.

Ramón wants to draw a systematic sample from a population of 5,000. He wants a sample size of 50. In this case, the sampling interval is _____.

The _____ provides a working definition of the target population. It is a comprehensive list of the elements from which the sample is drawn.

With this type of stratified sampling, the sample size from each stratum is determined independently without considering the size of the stratum relative to the target population size. The more important a particular stratum is considered, the higher will be the proportion of the sample elements selected from the stratum.

In drawing a _____sample, the selection of elements is based on some random procedure that gives elements a known and non-zero chance of being selected, thereby minimizing selection bias.

In which type of sampling method is the objective for the total sample to have proportional representation of the strata of the target population, and selection of elements is done on a convenience basis?

Cluster sampling puts the target population into different groups called clusters.

A ______ is a relatively small subset of the population, and it is drawn using either probability or non-probability procedures.

Explain the difference between a census and a sample and discuss why a sample may be preferred over a census.
