(C) The sample is unlikely to be representative of the American population.
(D) A random sample would be more likely to give a representative sample.
(E) If enough people call in, the large sample size will compensate for any other biases in the
sampling procedure.
Which of these would be a sampling technique for a well-designed survey of students in a high
school?
(A) Number each student on a list of all students’ names. Use a random number generator on a
calculator to randomly select 50 different numbers. The corresponding students will be in the
sample.
(B) Put up posters in the hallways and on classroom doors instructing students to text their responses
to a particular number. Those who respond will be in the sample.
(C) Have student council members ask the students in their third-hour class. The students in those
third-hour classes will be in the sample.
(D) Put a flyer on each student’s locker with the survey questions on it. Those who return their
responses to the office will be in the sample.
(E) Put a flyer with the survey questions on it next to the line in the cafeteria. Students can fill them
out and drop them in a box in the cafeteria. Those who return the surveys will be in the sample.
