  • B.chosen by throw of a dice
  • C.not randomly selected
  • D.selected at the last moment

Answer: C

A purposive sample is a non-probability sample because it is not randomly selected: the researcher chooses the subjects deliberately, according to the purpose of the study, so not every member of the population has a known chance of selection. It is not selected without any process, since the researcher applies a criterion, it is not chosen by a throw of a dice, which would be random, and it is not picked at the last moment, which would be an accidental or convenience selection.
