What is a convenience sample?

• A. A sample chosen randomly from a list of potential subjects
• B. A sample made up of subjects that are readily available
• C. A random selection of participants from a diverse population
• D. A method used to ensure a representative sample

Answer: (B)

A convenience sample is defined as a group of subjects selected because they are easily accessible or readily available to the researcher. This sampling method is often used in research when time, budget, or logistical constraints make it difficult to gather a more randomized or representative sample. For example, if a researcher conducts a study using students from a particular university, they may choose participants who are currently attending the institution without considering their demographic diversity, simply because these individuals are nearby and available for participation. This method can lead to potential bias, as it may not adequately represent the larger population. However, it can be useful in exploratory research or pilot studies where the main aim is to gather preliminary data quickly. The other options describe different sampling techniques that emphasize randomness or representativeness, which are not characteristics of a convenience sample.
