Question

Quizplus · Accepted Answer

True random samples are rarely used because researchers rarely have access to the entire population. It is often impractical and costly to try to survey or collect data from every member of a population. Therefore, researchers opt for more practical sampling methods such as convenience sampling, which is easier and quicker to carry out. However, convenience sampling may not be as representative of the population as true random samples.
