Quizplus · Accepted Answer

Arbitrary sample sizes are not efficient or economical because they do not take into account the characteristics of the population being surveyed, which can result in a larger sample size than necessary or an insufficient sample size to accurately represent the population. Therefore, other sampling methods, such as stratified or cluster sampling, may be more efficient and economical in achieving more accurate results.
