Quiz on Sampling, Sample Frame, and Sample Size

What is the primary purpose of sampling in research?

• To select the entire population

• To estimate or predict information about a larger population

• To eliminate bias in research

• To increase the sample size

What does the sample frame represent?

• The characteristics of the sample

• The entire population of interest

• The statistical significance of the research

• The sample size required

Which of the following is a factor that influences sample size?

• The number of researchers involved

• The desired level of statistical significance

• The funding available for the research

• The geographic location of the study

What is an example of probability sampling?

• Convenience sampling

• Purposive sampling

• Quota sampling

• Simple random sampling

Which sampling technique involves selecting every kth element from the population?

• Stratified sampling

• Systematic sampling

• Cluster sampling

• Multistage sampling

What is a key consideration to ensure the validity of research findings?

• Conducting research in multiple locations

• Using non-probability sampling techniques

• Ensuring the sample is representative of the target population

• Using a large sample size only

What is the main characteristic of non-probability sampling?

• Known chance of selection for each individual

• Equal chance of selection for all units

• Selection based on unknown probabilities

• Random selection of participants

Which of the following is NOT a type of probability sampling?

• Simple random sampling

• Stratified sampling

• Cluster sampling

• Convenience sampling

What is the first step in the sampling process?

• Calculate the sample size

• Select the sample

• Define the target population

• Establish the sample frame

What should researchers document during the sampling process?

• The opinions of the participants

• The sampling technique and any issues encountered

• Only the sample size

• The funding sources for the research
