A voluntary response sampling is a sampling in which people volunteer to participate in a survey. This is a form of biased sampling. It is impossible to get random sample using this sampling method.Know More
Voluntary response sampling is heavily biased because it focuses on volunteered survey answers rather than a random sampling. What makes this biased is because the only people who volunteer are those who have a particular interest in the topic of the survey. For example, if the survey is about feelings surrounding a particular religion, only those who feel strongly about it volunteer. This means that the resulting samples have two extreme sides with few or no middle-of-the-road responses to mellow out the results. This results in a sample that is not representative of the population. The bias often skews negative, as well.
Voluntary response sampling is useful for supporting a biased stance. For instance, if a website is anti-war and puts out a poll to its users, its users are also likely to be anti-war. The results of the poll, then, would have an anti-war view point, which the website can then cite as evidence that a population supports their views. In this way, voluntary response sampling can help research that has an agenda.Learn more in Psychology
