Quizplus · Accepted Answer

Randomly assigning individuals to groups helps ensure that the sample is representative of the larger population, which can reduce sampling error. A convenience sample (A) is not representative of the larger population and will likely introduce sampling error. Decreasing sample size (C) increases the likelihood of sampling error, as smaller samples are typically less representative than larger samples. Asking friends to answer a questionnaire (D) is likely to introduce bias, as friends may not be representative of the larger population.
