Which method describes respondents who are conveniently available and do not involve random selection?

• A. Convenience Sample
• B. Self-Selecting Sample
• C. Systematic Random Sample
• D. Purposive Sampling

Answer: (A)

Selecting respondents who are readily accessible and not using random selection is known as convenience sampling. It’s fast and inexpensive, making it useful when time, resources, or access are limited. Because participants are chosen for ease rather than representativeness, the results may be biased and not generalizable to the wider population. Other options operate differently: volunteers who opt in on their own are self-selecting and can skew results toward people with strong opinions or particular traits; choosing every nth person from a list with a random start is a systematic random approach that aims for representativeness; selecting participants based on specific characteristics to study a particular group is purposive sampling. The key idea here is convenience sampling relies on ease of access without any random selection.
