Question

Quizplus · Accepted Answer

Purposive, convenience, quota, and snowball sampling are all non-probability sampling techniques, which means they do not provide every member of the population with an equal chance of being selected for the sample. This can lead to systematic biases where certain people are over-represented or under-represented in the sample, making it difficult to generalize the findings to the broader population. Therefore, these techniques may result in samples where some people are systematically left out.
