Convenient, Voluntary and Destructive Sampling

Convenience Sample:

- One of the main types of non-probability sampling - Convenience samples consist of people who are easy for the poller/sampler to reach - Ex. A person decides to poll shoppers at a mall, because it is close to his/her home or business in distance - Ex. A person decides to poll people in an elevator because they are right beside him []

Voluntary Sample:

- One of the main types of non-probability sampling - A voluntary sample is made up of people who decide to self-select into the survey. - Normally those people would have a stronger interest in the subject of the poll or survey - Ex. When a person sets up a stand with a banner that reads their subject and says they have a survey. The people who voluntarily decide to take part in the sample make it a voluntary sample Ex. When a news station asks viewers to take part in an online poll    Destructive Sampling:

- Destructive sampling is when you completely destroy the test subject. - Generally used to test the strength or endurance of a product. Not used on people! - Ex: Blowing up a balloon until it pops.​  []
