To survey the opinions of the students at your high school, a researcher plans to select every twenty-fifth student entering the school in the morning. Assuming there are no absences, will this result in a simple random sample of students attending your school? O No, because not every sample of the intended size can possibly be selected. O Yes, because the 24 out of every 25 students who are not selected will form a control group. O Yes, because this is an example of systematic sampling, which is a special case of simple random sampling. O Yes, because every student has the same chance of being selected. O Yes, but only if there is a single entrance to the school.
