. A sampling frame is:

a summary of the various stages involved in designing a survey.

an outline view of all the main clusters of units in a sample.

a list of all the units in the population from which a sample will be selected.

a wooden frame used to display tables of random numbers.

. A simple random sample is one in which:

from a random starting point, every nth unit from the sampling frame is selected.

a non-probability strategy is used, making the results difficult to generalize.

the researcher has a certain quota of respondents to fill for various social groups.

every unit of the population has an equal chance of being selected.

. It is helpful to use a multi-stage cluster sample when:

the population is widely dispersed geographically.

you have limited time and money available for travelling.

you want to use a probability sample in order to generalise the results.

all of the above.

. The standard error is a statistical measure of:

the normal distribution of scores around the sample mean.

the extent to which a sample mean is likely to differ from the population mean.

the clustering of scores at each end of a survey scale.

the degree to which a sample has been accurately stratified.

. What effect does increasing the sample size have upon the sampling error?

It reduces the sampling error.

It increases the sampling error.

It has no effect on the sampling error.

None of the above.

. Which of the following is not a type of non-probability sampling?

Snowball sampling

Stratified random sampling

Quota sampling

Convenience sampling

. What are some of the features making online communications, and therefore online surveys problematic?

Many people have more than one email address

Many people use more than one internet service provider (ISP)

A household may have one computer but several users

All of the above

. Which of the following is not a characteristic of quota sampling?

The researcher chooses who to approach and so might bias the sample

Those who are available to be surveyed in public places are unlikely to constitute a representative sample

The random selection of units makes it possible to calculate the standard error

It is a relatively fast and cheap way of finding out about public opinions

. The findings from a study of training and skill development among employees of a company can be generalised to the population of:

All employees of that company

All employees in that industry

All unskilled employees in that industry

All graduate-level employees

. The term 'data processing error' refers to:

activities or events related to the sampling process, e.g. non-response.

faulty techniques of coding and managing data.

problems with the implementation of the research process.

the unavoidable discrepancy between the sample and the population.
