What are the advantages of convenience sampling?

Back

Convenience sampling is quick, easy, and cost-effective, making it useful for preliminary research or when time and resources are limited.

Front

What are the disadvantages of convenience sampling?

Back

Convenience sampling can lead to bias and may not accurately represent the population, limiting the generalizability of the results.

Front

In what situations is systematic sampling most useful?

Back

Systematic sampling is useful when a complete list of the population is available and when the population is homogenous.
