Explain why probability samples are likely to have less sampling error than convenience samples.
What will be an ideal response?
Ans: Answers vary
Probability samples are chosen such that likelihood of any single individual being selected for the sample is known, because participants are chosen at random from the population or subgroups of the population. Convenience samples are chosen based on who is available and willing to participate in a study. Thus, the probability sample is more likely to represent the population overall and contain less sampling error.
