Voluntary response samples are things like mail-out surveys. The participants could choose to participate or not. This causes some forms of bias, because the only participants usually have strong opinions on the subject. People who care less are less likely to respond, leaving them out of the demographic.
No they aren't.
People with a special interest are more likely to respond, so the sample is likely to be biased.
Voluntary response sample is not generally suitable for statistical study because its results are not likely to be the representative of the entire population under study.Such results could be biased as those who made effort to respond voluntary have strong feelings or opinions whether favorable or unfavorable regarding the subject of consideration.
An example of voluntary response sample would be when a radio talk-show decides to run a call-in survey on a controversial topic, such as gun control. The most likely callers are going to be people with the strongest opinions, thus the sample that results from the survey is going to over-represent those very people.
