Detailed explanation-1: -Volunteer sampling is a sampling technique where participants self-select to become part of a study because they volunteer when asked, or respond to an advert.
Detailed explanation-2: -A voluntary response sample is defined as a type of sample made up of self-chosen participants. These participants volunteer to take part in different research studies to share their opinions on topics that interest them. A voluntary response sample is made up of persons who volunteer to take research surveys.
Detailed explanation-3: -Voluntary response bias is referring to how allowing your sample to self-select skews your data, and you don’t actually get results that are representative of your whole population.
Detailed explanation-4: -Volunteer sampling involves asking for volunteers – for example, advertising your study on a notice board or on Facebook and using anyone who signs up. Because they have volunteered, this sort of sample might be more committed than a sample that has to be approached and asked.
