What are the three factors that contribute to volunteer bias? *

Three factors that contribute to volunteer bias are: 1) privileges of the study participants and 2) having high energy and 3) being vested in the survey or research question.

Explanation:

Volunteer bias refers to the kind of bias that happens when volunteers are not likely to represent the general population.  Volunteers may be more likely to be unemployed for example or they might be more likely to be women.  It has been noted that project volunteers also tend to be high in agree-ableness and they are open to new experiences in terms of their personalities.  This presents a problem when researchers want their same to be a general representation of the population. We should also consider the characteristics and lifestyles of those who decline from participating or who do not volunteer to really get a sense of the general population.
