Exam 6: Sampling

It is important to use a ______ sample when sampling error is likely to be large.

Unlike a stratified random sample, the ______ sample will make use of convenience sampling techniques such as recruiting participants from a participant sign-up pool or asking students sitting in the library to fill out the survey.

Convenience samples are also called ______.

Convenience samples likely increase the amount of sampling error in the study, lowering its ______.

Volunteers are selected from students such that the proportion of students in each age range in the sample matches the proportion in the population, using ______ type of sampling.

Convenience samples will likely increase the amount of sampling error in the study, lowering its ______ validity by making a test of the hypotheses less accurate.

In convenience samples the probability of an individual being chosen from the population cannot be determined, because individuals are ______.

In a simple random sample, if a population has 100 individuals, the chance of any one individual being selected for the sample is ______.

A disadvantage of cluster sampling is that a portion of the population may be missed in the sample, giving the researcher a sample that is not fully representative of the population.

Students are selected at random from lists of students at a university organized by class level such that the proportion of individuals at each class level in the population of students matches the proportion selected for the sample. This type of sampling is ______.

Internet samples are typically less representative of the population of interest than samples that are collected face-to-face.

All sampling error can be removed from a study if the appropriate sampling technique is used.

Convenience samples make it more difficult to generalize the results of the study to the population, lowering its ______.

Stratified random sampling ensures equal probability of being chosen from a large population.

Many researchers have argued that results from psychological studies using volunteer college students for samples are not informative about the behavior in the general population.

External validity of a study should be considered when conclusions are drawn from results collected with a convenience sample.

The sampling technique that involves choosing individuals from the population at random where the proportions of members of different groups are the same in the population and the sample is ______.

One way to fix the problem of lessened representativeness in cluster sampling is to ______ of clusters in the sampling procedure.

Kahn and Schlosser (2010) study of doctoral students stratified programs ______ and ______.

The sampling technique that involves choosing individuals from the population such that individuals from the population who volunteer are selected ______.
