Detailed explanation-1: -Opportunity sampling is a sampling technique used to select participants from a target group to take part in a research study. It consists of the researcher selecting anyone who is available and willing to take part in the study.
Detailed explanation-2: -Opportunity sampling is where a researcher selects participants based on their availability. One example would be standing on the street asking passers by to join the research. This is a quick and easy way to access a sample, so practicality is an advantage.
Detailed explanation-3: -Convenience sampling (also known as availability sampling) is a specific type of non-probability sampling method that relies on data collection from population members who are conveniently available to participate in study. Facebook polls or questions can be mentioned as a popular example for convenience sampling.
Detailed explanation-4: -Convenience sample: The researcher chooses a sample that is readily available in some non-random way. Example-A researcher polls people as they walk by on the street.
Detailed explanation-5: -Snowball sampling helps researchers find a sample when they are difficult to locate. Researchers use this technique when the sample size is small and not easily available.
