Exam 9: Sampling Methods and Sample Size

Cluster sampling is often associated with area sampling.

Significant advantages of sampling include cost savings, time economy, more in-depth information, lower total error, greater practicality, and greater security.

The large group of interest to the researcher is called the sample.

The sampling frame is

Non-statistical methods of determining sample size includes all of the following except

The steps of the sampling decision model include all of the following except

The choice of sample size for a probability sample is made on a statistical basis.

The statistical methods of establishing sample size apply only to probability samples.

Statistical methods of determining sample size include using a previous sample size, using a typical sample size, and using a magic number.

A census is the term that refers to the group surveyed any time the survey is not administered to all members of the population

The size of the sample will be a function of the timeliness of the sample.

Sample bias cannot be reduced by increasing the sample size.

The sampling frame cannot be the process used to select the sample.

"Ask an expert" is a statistical approach for establishing appropriate sample size.

Despite difficulty in knowing if the sample is representative of the population, the _____ is frequently used, particularly for exploratory research.

In a stratified sample the total population is divided into mutually exclusive subgroups and a simple random sample is then chosen from each subgroups.

Cluster sampling is not associated with area sampling.

Whether a sample is a probability sample or a nonprobability sample, the important aspect is to obtain as much representative information as possible and eliminate as much sampling and nonsampling error as possible.

Companies that do repeated studies over time to gather similar information to compare data and determine trends tend to use _____ to determine the sample size for the current study.

The conveniences sampling techniques is frequently used in explanatory research.
