Sampling Methods

Front

What is a systematic sampling method?

Back

A sampling method where every nth individual is selected from a list or queue, such as interviewing every 10th student.

Front

Define cluster sampling.

Back

A sampling method where the population is divided into groups (clusters) and a whole cluster is randomly selected for the survey.

Front

What is simple random sampling?

Back

A sampling method where every individual has an equal chance of being selected, ensuring that every possible group of the required size has the same chance of selection.

Front

Explain stratified sampling.

Back

A sampling method that involves dividing the population into subgroups (strata) and then taking a fixed number of samples from each subgroup using simple random sampling.

Front

What is convenience sampling?

Back

A non-probability sampling method where samples are taken from a group that is easily accessible.

Front

What is voluntary response sampling?

Back

A sampling method where individuals choose to participate in the survey, often leading to biased results.

Front

How does systematic sampling differ from simple random sampling?

Back

Systematic sampling selects individuals at regular intervals, while simple random sampling gives every individual an equal chance of selection without a fixed interval.

Front

What is the main advantage of stratified sampling?

Back

It ensures that all subgroups of the population are represented in the sample, leading to more accurate and reliable results.

Front

Provide an example of cluster sampling.

Back

A teacher randomly selects one class from a school to survey the entire class's performance.

Front

What is the disadvantage of convenience sampling?

Back

It may not accurately represent the population, leading to biased results.
