Which code represents Volunteer Sample?

Which code represents Volunteer Sample?

• A. MO
• B. VO
• C. IO
• D. IU

Answer: (B)

Volunteer samples are defined by participants choosing to participate themselves, i.e., self-selection. In this coding scheme, the label that signals that voluntary, self-selected nature uses the V element to denote Volunteer. The code that starts with V (VO) best matches this concept, so it’s the correct designation for Volunteer Sample. The other codes do not reflect self-selection, so they don’t fit Volunteer Sample.
