## Statistics

Kind of sampling method to be used as well as its advantages.

The registrar of a college with a population of N=4,000 full-time students is asked by the president to conduct a survey to measure gratification with the quality of life on campus. The table below contains a breakdown of the 4,000 registered full time students by gender as well as class designation

 Class Designation Gender Fr. So Jr Sr Total Female 700 520 500 480 2,200 Male 560 460 400 380 1,800 Total 1260 980 900 860 4000

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 describe what type of sample could you take? Discuss.

2) describe what are the advantage of selecting a simple random sample in (a)?

3) describe 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.
