Question

Quizplus · Accepted Answer

Random sampling is the best choice when making statements about the larger population because every member of the population has an equal chance of being selected. This reduces the risk of bias in the sample and allows for more generalizable results. Convenience sampling (A) relies on selecting subjects that are easily accessible, which can introduce bias. Cluster sampling (B) involves selecting subgroups within a population, which can also introduce bias if the clusters are not representative of the larger population. Stratified sampling (D) involves dividing the population into subgroups based on certain characteristics and then sampling within each subgroup. While this can be useful for ensuring representation of specific groups, it may not be necessary for making statements about the larger population.
