The registrar intends to take a probability sample of students and project the results from the sample to the entire population of full-time students.
a. If the frame available from the registrar's files is an alphabetical listing of the names of all N = 4,000 registered fulltime students, what type of sample could you take? Discuss.
b. What is the advantage of selecting a simple random sample in (a)?
c. What is the advantage of selecting a systematic sample in (a)?
d. If the frame available from the registrar's files is a listing of the names of all N = 4,000 registered full-time students compiled from eight separate alphabetical lists, based on the gender and class designation breakdowns shown in the class designation table, what type of sample should you take?
