Quizplus · Accepted Answer

A representative sample is a group of subjects that is randomly selected from the population of interest and matches the population on important characteristics such as age and sex. This helps to ensure that the results of the study are applicable to the entire population and reduces the likelihood of sampling bias. Volunteer bias refers to the fact that people who volunteer for research studies may differ in important ways from those who do not, potentially affecting the generalizability of the results. The experimental group and the control group are specific groups within a research study and are not relevant to the question asked.
