Exam 10: Sampling: Sample Design and Sample Size

Small sample sizes increase the risk of systematic error.

Priming respondents to respond in a particular manner can introduce systematic error into a research study.

Projecting data beyond the sample is inappropriate in which of the following sampling techniques?

One potential source of sample selection error is the discrepancy between the definition of the population and the sampling frame.

Simple random sampling requires complex computer programs to conduct the sample selection.

In stratified sampling, the stratification variables are usually metric (continuous) in nature.

A researcher wants to recruit respondents who are amateur boxing fans. The researcher first speaks to some experts in amateur boxing who give her ideas on venues and occasions where her population of interest may meet. She then goes to these venues to make contact with her target sample face-to-face. This researcher is using:

Population is a subset of a sample.

If Virgin Australia randomly selects a set of 10 flights on a given day, then randomly selects a groups of 10 passengers on each of these flights to participate in an in-flight survey, then the passengers are a:

The first stage of selecting a sample is to decide whether to use a probability or nonprobability sampling method.

If a researcher sets up an interviewing booth from which to intercept shoppers at a shopping centre, which type of sampling procedure is being used?

All inferential statistics assume that the true population is finite in size.

Sample size affects both sampling and non-sampling errors.

The head of a marketing research department instructs field interviewers to interview owners of DVD players in a shopping centre. They are instructed to each interview 15 Sony owners, 18 Panasonic owners, 10 Toshiba owners and 12 owners of other brands. Which type of sampling procedure does this represent?

When conducting telephone surveys, randomly selecting contacts (for example, from the White Pages) helps to eliminate sampling frame errors.

Suppose that a researcher implements a study in which it was planned that simple random sampling from a sampling frame would be used, but a systematic sample from the sampling frame is used instead. What has occurred?

Non-sampling errors are errors resulting from aspects of the research that cannot be controlled.

When determining sample size, the precision level of the estimate is indicated by the:

An approach for verifying measurements by taking the same measure from different outlook is:

A statistical fluctuation that occurs because of chance variations in the elements selected for a sample is known as a:
