Exam 9: Sampling

Simple random sampling is NOT a wise choice when you have:

95 percent of the observations under the normal curve fall within ________ times the sample error.

If the strata sample sizes are faithful to their relative sizes in the population, you have what is called a proportionate stratified sample design.

One of the advantages of systematic sampling is that:

Which of the following does the textbook note as the proper way to calculate sample size?

Which of the following is NOT a practical constraint that may force sample size adjustments?

Sample size does not have to be "huge" in order to have reasonably accurate data. For example, samples that are 500 or less may provide reasonably accurate information.

Snowball sampling is another name for:

If we define our population as all households in the city of Montreal, Quebec, and we use the Montreal telephone directory from which to draw our sample, we would likely have:

Which of the following is the best definition of variability?

In area sampling, the one-step approach is applied if the researcher believes that the various geographic areas (or clusters) are sufficiently identical.

Nonresponse refers to:

The sample size determines:

A master list of all the members of the population is known as the:

A graph of the relationship between accuracy and size of the sample shows that accuracy decreases as sample size increases.

If a random start is used in terms of visitors to a website, and then a skip interval is used to skip to the next visitor to ask to participate in a survey, this is an example of:

To cope with the realities of incidence rate and nonresponse, researchers should use:

What three factors are needed to calculate sample size?

It is an ethical marketing researcher's responsibility to try to educate a client on the wastefulness of excessively large samples.
