Question

Quizplus · Accepted Answer

Dr. Jacobs is planning to obtain a representative sample, which means selecting people from different segments of the population in proportions that are reflective of the actual demographic distribution. This is important to ensure that the results of the survey are not skewed by a biased sample that underrepresents or overrepresents certain groups. A natural clinical trial does not apply in this scenario, and equated population and biased sample are not terms commonly used in survey research.
