What type of sampling method was used in the practical described?

• A. Random sampling
• B. Opportunity sampling
• C. Stratified sampling
• D. Systematic sampling

Answer: (B)

Opportunity sampling is a method where researchers select participants based on their availability and willingness to participate in the study. This approach is often used when researchers need to gather data quickly and efficiently, making it a practical choice for many studies in the field of psychology. This type of sampling relies on the most accessible subjects, which may include individuals who are present in a specific location or situation at a particular time.

In contrast, the other sampling methods are more structured and systematic. Random sampling involves selecting individuals randomly from a larger population, ensuring that every member has an equal chance of being chosen, which can lead to a more representative sample. Stratified sampling requires dividing the population into distinct subgroups and then sampling from each subgroup proportionally, ensuring that the sample reflects the diversity of the population. Systematic sampling involves selecting every nth participant from a list or group, which also adds a level of structure.

Opportunity sampling’s reliance on availability often makes it more convenient, but it does have limitations in terms of generalizability and potential bias since it may not represent the broader population accurately. Knowing this context can help in understanding why opportunity sampling was the chosen method in the practical described, highlighting its practical applications and inherent disadvantages.
