Opportunity

• Opportunity sampling is when the researcher chooses participants who are members of the target population "" and are willing and able to participate. This is done by approaching and asking members of the target population "" if they would like to partake. The researcher continues until they have the desired number "" of participants.
• A strength of opportunity sampling is that it is the easiest and most convenient method as you use the first participants you find which means it take less effort and is less time consuming to acquire your sample compared to other techniques
• A weakness of opportunity sampling is that it is less representative than other methods as it'll only represent those who are in the vicinity of where the researcher sought out participants. It will only reflect members of the target population who were present at the time. Because it is less representative the findings will be less generalisable to the target population
• A weakness of opportunity sampling is that the sample may be biased as the investigator has full control over who they choose to be part of the sample. They may pick participants that they think will support their hypothesis
