Exam 14: Sampling Fundamentals

An approach in which each population member, and thus each possible sample, has an equal probability of being selected is known as.

There are no justifications for using a convenience sample.

Sampling frame is a list of population members used to obtain a sample.

Sampling error is the difference in value between the population parameter and the sample statistic that occurs because of sampling.

What common characteristics do the three non-probability sampling techniques possess?

It is possible for on-line and traditional research methods to yield similar results

One technique for dealing with not-at-home is to predict their responses from a knowledge of respondents' frequency of being away from home.

Researchers prefer sampling to census when

One way to stratify in a shopping center intercept study is by time segments.

Sample size is typically small in case of ____________ research

"Target population" is another term meaning "sample."

Census is appropriate if the population size is large and the cost and time associated with obtaining the information is high.

For most studies, more than one target population can be defined.

A researcher who is faced with the problem of non-response can attempt to reduce the potential bias of the results by

The term "sampling unit" is always used to refer to a "respondent."

Stratified sampling is useful when subgroups can be identified as representative of the whole population.

One way to overcome the problem of unlisted telephone numbers is to dial numbers randomly.

Which of the following is the most cost-effective probability sampling technique?

Non-probability sampling allows the researcher to explicitly identify possible biases.

In cluster sampling, a random sample of subgroups is selected and all members of the subgroups become part of the sample.
