Convenience samples likely increase the amount of sampling error in the study, lowering its ______.

B) external validity
C) power
D) probability

Question

Quizplus · Accepted Answer

Convenience sampling is a non-probability sampling method, which means there is no way to ensure that the sample is representative of the population being studied. This lowers the internal validity of the study because it increases the chance that the results are due to random variation or other factors that are unrelated to the study's variables. It does not necessarily lower external validity because convenience sampling can still produce results that can generalize to other populations or situations. Power and probability are not directly affected by convenience sampling.
