• None of the above

“Controlled Group” is a term used in _______

• Survey research

• Historical research

• Experimental research

• Descriptive research

How would you define 'the research process'?

• The researcher's plan of action to be followed when carrying out research.

• A method of collecting research data.

• The stages or steps the researcher follows in carrying out a research project.

• The account of a study the researcher will write at the end of the study ready for publication.

What is a research design?

• A way of conducting research that is not grounded in theory

• The choice between using qualitative or quantitative methods

• The style in which you present your research findings, e.g. a graph

• A framework for every stage of the collection and analysis of data

Which of the following is not true about stratified random sampling?

• It involves a random selection process from identified subgroups

• Proportions of groups in the sample must always match their population proportions

• Disproportional stratified random sampling is especially helpful for getting large enough subgroup samples when subgroup comparisons are to be done

• Proportional stratified random sampling yields a representative sample

Which of the following statements are true?

• The larger the sample size, the greater the sampling error

• The more categories or breakdowns you want to make in your data analysis, the larger the sample needed

• The fewer categories or breakdowns you want to make in your data analysis, the larger the sample needed

• As sample size decreases, so does the size of the confidence interval

Which of the following is not a form of nonrandom sampling?

• Snowball sampling

• Convenience sampling

• Quota sampling

• They are all forms of nonrandom sampling

Which of the following will give a more “accurate” representation of the population from which a sample has been taken?

• A large sample based on the convenience sampling technique

• A small sample based on simple random sampling

• A large sample based on simple random sampling

• A small cluster sample

People who are available, volunteer, or can be easily recruited are used in the sampling method called ______.

• Simple random sampling

• Cluster sampling

• Systematic sampling

• Convenience sampling

Which of the following would usually require the smallest sample size because of its efficiency?

• One stage cluster sampling

• Simple random sampling

• Two stage cluster sampling

• Quota sampling
