Question

Quizplus · Accepted Answer

A haphazard sample is also known as a convenience sample, which is not a probability sample because it does not involve random selection. Instead, the individuals or items are chosen based on ease of access or availability, which can introduce bias into the sample. A simple random sample, stratified random sample, and cluster sample are all probability samples because they involve random selection of individuals or groups.
