The registrar means to take a probability sample of n= 200 students as well as project the results from the sample to the entire population of full time students.
1) If the frame available from the registrar's files is an alphabetical listing of the names of all N=4000 registered full time students explain what type of sample could you take? Discuss.
2) Explain what are the advantage of selecting a simple random sample in (a)?
3) Explain what is the advantage of selecting a systematic sample in (a)?
4) If the frame available from the registrar's file is a listing of the names of all N=4000 registered full time students compiled from eight separate alphabetical lists, based on the gender as well as class designation breakdown shown in the class designation table and what type of sample should you take? Discuss
Suppose that each of the N=4,000 registered full time students lived in one of the 20 campus dormitories. Each dormitory comprises four floors, with 50 beds per floor, and so accommodates 200 students. It is college policy to completely integrate students by gender and class designation on each floor within each dormitory and what type of sample should you take? Discuss.
