Sampling Methods Quiz

Which of the following is a method of random sampling?

• Convenience sampling

• Stratified sampling

• Quota sampling

• Snowball sampling

What is the main characteristic of simple random sampling?

• Every member of the population has an equal chance of being selected

• The population is divided into subgroups

• Participants are chosen based on ease of access

• Participants refer other participants

Which sampling method involves dividing the population into subgroups and then taking a sample from each subgroup?

• Systematic sampling

• Cluster sampling

• Stratified sampling

• Convenience sampling

Which of the following is an example of non-random sampling?

• Simple random sampling

• Systematic sampling

• Cluster sampling

• Purposive sampling

• Simple random sampling

• Systematic sampling

• Cluster sampling

• Stratified sampling

Which of the following best describes cluster sampling?

• The population is divided into clusters, and a random sample of clusters is selected

• The population is divided into strata, and a random sample is taken from each stratum

• Every member of the population has an equal chance of being selected

• Participants are chosen based on ease of access

What is sampling bias?

• The tendency to favor certain outcomes over others

• The process of dividing the population into subgroups

• The use of random number generators to select samples

Which of the following is a potential source of sampling bias?

• Using a random number generator

• Selecting participants based on convenience

• Dividing the population into strata

• Ensuring every member has an equal chance of selection

How can random sampling techniques help reduce bias?

• By ensuring every member of the population has an equal chance of being selected

• By selecting participants based on specific characteristics

• By dividing the population into clusters

• By using non-random methods

Which of the following is an example of applying a random sampling technique?

• Selecting participants who are easily accessible

• Using a random number generator to select participants

• Choosing participants based on specific criteria

• Asking participants to refer others
