What is voluntary response bias?
- When sample participants are self-selected volunteers, as in voluntary samples, voluntary response bias emerges.
- An illustration would be call-in radio programs that invite listeners to participate in polls on contentious issues (abortion, affirmative action, gun control, etc.).
- The sample that results tends to overrepresent people with strong opinions. In a random sampling technique, every component of the population has a known, non-zero probability of being chosen, and the selection of the sample unit is dependent only on chance.
- By removing voluntary response bias and protecting against undercoverage bias, random sampling aids in the production of representative samples.
- Random sampling underpins all probability sampling techniques.
