Question

Choose the non-probability sampling method where the sample is taken from a group of people easy to contact or reach.

• A. Simple random sampling
• B. Snowball sampling
• C. Convenience sampling
• D. Stratified random sampling

Hint:

Remember: If the sample is chosen because it is easy to reach, it is always Convenience Sampling.

Answer 1

The Correct Option is C

Step 1: Understanding non-probability sampling.
Non-probability sampling methods are those where not every member of the population has an equal chance of being selected. The choice of sample is often based on accessibility, judgment, or availability.

Step 2: Definition of convenience sampling.
Convenience sampling is a type of non-probability sampling in which samples are selected from the part of the population that is easiest to access. For example, asking friends, classmates, or people nearby to participate in a survey.

Step 3: Why other options are incorrect.
- Simple random sampling (A): A probability method where every member has an equal chance of being chosen. Not based on convenience.
- Snowball sampling (B): Used when subjects are hard to locate; one participant refers the next. More useful in hidden populations.
- Stratified random sampling (D): A probability sampling method where population is divided into strata, and samples are taken proportionally. Not convenience-based. Thus, the method described in the question is clearly Convenience Sampling. \[ \boxed{\text{Convenience sampling}} \]
