Which sampling method involves selecting participants based on specific characteristics relevant to the research?

The sampling method that involves selecting participants based on specific characteristics relevant to the research is purposive sampling. This approach is specifically designed to ensure that the sample includes individuals who have certain attributes or experiences that are imperative for the study at hand.

In research, the goal is often to gather insights from individuals who can provide the most relevant and informative data related to the topic being investigated. Purposive sampling allows researchers to target a particular population segment that possesses the desired characteristics, thus enhancing the credibility and applicability of the findings.

This method is particularly useful in qualitative research or when exploring niche topics where understanding specific perspectives is crucial. By selecting participants purposefully, researchers can gain deeper insights that may not be achievable through random sampling methods, which do not take such criteria into account.
