Sampling Methods Quiz

What is the primary purpose of sampling in research?

• To increase the cost of research

• To eliminate all biases in research

• To represent a larger population with a smaller subset

• To collect data from every individual in a population

Which of the following is a type of probability sampling?

• Convenience sampling

• Quota sampling

• Stratified sampling

• Purposive sampling

What is a disadvantage of simple random sampling?

• It can lead to unrepresentative groupings by chance

• It is difficult to implement

• It is time-consuming

• It requires advanced statistical knowledge

In systematic sampling, how is the first item chosen?

• It is predetermined by the researcher

• It is chosen based on convenience

• It is the first item on the list

• It is selected randomly

What does stratified sampling aim to achieve?

• Random selection of individuals

• Reduction of sampling errors

• Equal representation of all subgroups

• Convenience in data collection

Which sampling method involves selecting entire groups at random?

• Systematic sampling

• Simple random sampling

• Cluster sampling

• Convenience sampling

What is a key characteristic of non-probability sampling?

• Every member has a known chance of selection

• Selection is based on randomization

• It often introduces bias

• It is always more accurate than probability sampling

What is the main advantage of convenience sampling?

• It is quick and easy to implement

• It ensures a representative sample

• It eliminates all biases

• It provides detailed insights

Which method is best for studying hard-to-reach populations?

• Systematic sampling

• Simple random sampling

• Snowball sampling

• Stratified sampling

What is the first step in choosing a sampling method?

• Get feedback from peers

• Determine the reach of your findings

• Define your research goals

• Assess the nature of your population
