Which sampling method involves selecting participants who are most easily available at the time of the study?

• A. Random Sampling
• B. Opportunity Sampling
• C. Volunteer Sampling
• D. Systematic Sampling

Answer: (B)

Choosing participants who are easiest to recruit at the moment is opportunity sampling. It’s a quick, practical approach because you simply approach and include whoever is nearby or willing to participate, without any random selection. The trade-off is that this method can introduce bias and limit generalizability, since the sample may not represent the broader population. It differs from random sampling (every member has an equal chance), systematic sampling (following a fixed rule, like every nth person), and volunteer sampling (participants self-select). For a quick study or pilot, opportunity sampling is common, but findings should be interpreted with caution due to potential bias.
