Explanation:
Detailed explanation-1: -Subject to bias: Voluntary sampling is highly susceptible to bias, because researchers make little effort to control sample composition.
Detailed explanation-2: -CONVENIENCE SAMPLING – Subjects are selected because they are easily accessible. This is one of the weakest sampling procedures. An example might be surveying students in one’s class. Generalization to a population can seldom be made with this procedure.
Detailed explanation-3: -Convenience sampling (also known as grab sampling, accidental sampling, or opportunity sampling) is a type of non-probability sampling that involves the sample being drawn from that part of the population that is close to hand.
