Quizplus · Accepted Answer

A random sample ensures that each member of the population has an equal chance of being selected, which reduces bias in the sample. This is in contrast to convenience or voluntary response samples, which may under or over-represent certain groups in the population. Small or expensive samples do not necessarily reduce bias.
