Arbitrary sample size approaches rely on erroneous rules of thumb.

Question

Quizplus · Accepted Answer

Arbitrary sample size approaches involve using rules of thumb such as "use a sample size of 30" or "use a sample size of 10% of the population", without any statistical reasoning or calculation. These approaches can lead to biased or unreliable results as they do not consider the specific characteristics of the population or the research question. Therefore, they are considered erroneous.
