Quizplus · Accepted Answer

Using a random sample is not a non-statistical method of determining sample size. A random sample is a statistical method of selecting a sample. A, B, and C are non-statistical methods that do not take into account the variability or uncertainty in the population. The best choice for determining sample size is to use statistical methods, such as calculating the necessary sample size based on desired level of statistical significance and effect size.
