What is a sampling method?

Back

A sampling method is a technique used to select individuals or groups from a larger population to participate in a study or survey.

Front

Define voluntary response sampling.

Back

Voluntary response sampling is a method where individuals choose to participate in a survey or study, often leading to biased results as it attracts those with strong opinions.

Front

What is convenience sampling?

Back

Convenience sampling is a non-probability sampling method where samples are taken from a group that is easily accessible, which may not represent the entire population.

Front

Explain stratified sampling.

Back

Stratified sampling involves dividing the population into subgroups (strata) and randomly sampling from each stratum to ensure representation of all groups.

Front

What is systematic sampling?

Back

Systematic sampling is a method where you select every nth individual from a list or sequence, starting from a random point.

Front

Describe simple random sampling (SRS).

Back

Simple random sampling (SRS) is a method where every individual in the population has an equal chance of being selected, ensuring unbiased representation.

Front

What are the advantages of stratified sampling?

Back

Stratified sampling increases the precision of the results by ensuring that all subgroups are represented, reducing sampling error.

Front

What is a potential drawback of convenience sampling?

Back

Convenience sampling can lead to biased results as it may not accurately reflect the diversity of the entire population.

Front

How does voluntary response sampling affect survey results?

Back

Voluntary response sampling can skew results as it tends to attract individuals with strong opinions, leading to overrepresentation of those views.

Front

What is the main goal of using systematic sampling?

Back

The main goal of systematic sampling is to create a sample that is easy to obtain while maintaining a level of randomness.
