Class Work #30 - Sampling Methods

Front

What is a convenience sampling method?

Back

A convenience sampling method involves selecting individuals who are easiest to reach or sample, rather than using a random selection process.

Front

Define Simple Random Sampling (SRS).

Back

Simple Random Sampling (SRS) is a sampling method where every individual has an equal chance of being selected, often achieved through random number generation.

Front

What is 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.

Front

Explain stratified sampling.

Back

Stratified sampling involves dividing the population into distinct subgroups (strata) and randomly sampling from each subgroup to ensure representation.

Front

What is cluster sampling?

Back

Cluster sampling is a method where the population is divided into clusters (often geographically), and entire clusters are randomly selected for the study.

Front

How does systematic sampling work?

Back

Systematic sampling involves selecting every nth individual from a list or sequence, starting from a randomly chosen point.

Front

What is the main advantage of using SRS?

Back

The main advantage of SRS is that it minimizes bias and allows for generalization of results to the larger population.

Front

When is convenience sampling useful?

Back

Convenience sampling is useful when time and resources are limited, but it may not provide a representative sample.

Front

What is a potential drawback of voluntary response sampling?

Back

A potential drawback of voluntary response sampling is that it can lead to self-selection bias, where only those with strong opinions participate.

Front

Describe a scenario where stratified sampling would be appropriate.

Back

Stratified sampling is appropriate when a researcher wants to ensure representation from different demographic groups, such as age or gender.
