Question

Quizplus · Accepted Answer

A random sample is the best choice for representing the larger population because it ensures that every member of the population has an equal chance of being selected for the sample. This helps to minimize bias and increase the reliability and validity of the results. Convenience samples may not be representative of the population and may introduce bias, while samples with unique characteristics may not be generalizable to the larger population. Treatment blocks are used in experimental design to reduce variability within groups, but do not represent the larger population.
