Milo wants to survey college freshmen about their alcohol use.He stands outside of a fraternity house and surveys people entering the house.This situation is an example of

A) accidental sampling.
B) purposive sampling.
C) snowball sampling.
D) quota sampling.

Accidental or convenience sampling involves selecting participants who are readily available and accessible. In this case, Milo is simply surveying people entering the fraternity house without any deliberate attempt to select a specific group of people. Therefore, the best choice is accidental sampling. Purposive sampling involves selecting participants based on a specific characteristic or criterion, snowball sampling involves relying on participants' referrals to recruit others, and quota sampling involves stratifying the population and ensuring that the sample reflects the proportionate representation of each stratum. None of these methods are evident in the scenario described.
