Question

Quizplus · Accepted Answer

A sample is a subset of a population that is selected for research purposes. In this case, Dr. Ziser cannot include all people above the age of 80, so she will need to select a sample of participants in order to conduct her experiment. A census would involve gathering data from the entire population (in this case, all people above the age of 80), which is not feasible for this experiment. A population refers to the entire group of individuals or objects that the research is interested in, which in this case is all people above the age of 80. A subgroup is a smaller group within a larger group, so it is not the best choice for this situation.
