Which sampling type is defined as a sample selected on the basis of members' own action in arriving at the sampling point?

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

Answer: (A)

Self-selecting sampling happens when people choose to participate on their own by showing up at the sampling point or volunteering. Their own initiative in deciding to take part defines this method, often after responding to a call or advertisement. This differs from a convenience sample, which is chosen mainly because participants are easy to reach, regardless of whether they actively sought out the study; purposive sampling, where the researcher hand-picks participants for specific characteristics or expertise; and snowball sampling, where existing participants recruit others they know. The description given matches the idea that members’ own action in arriving at the sampling point determines inclusion.
