A simple random sample is a method used by pollsters to select a representative sample in which every individual in the population has an equal probability of being selected as a respondent. This means that the sample is not biased towards any particular group or characteristic, which helps to ensure accurate and reliable results. Stratified samples divide the population into subgroups based on certain characteristics, and then select samples from each subgroup in proportion to their representation in the population, while a quota sample is a non-probability sampling method in which the researcher selects participants based on pre-determined quotas for certain characteristics such as age or gender. Therefore, the best choice is a simple random sample.
