On a large college campus first-year students and sophomores live in dorms located on the eastern part of the campus and juniors and seniors live in dorms located on the western part of the campus. suppose you want to collect student opinions on a new housing structure the college administration is proposing and you want to make sure your survey equally represents opinions from students from all years.

Remainder Part:

(a) What type of study is this?

(b) Suggest a sampling strategy for carrying out this study?

A. Observational Study

B. Stratified Sampling

Explanation:

Requirement A. I have to carry an Observational study because in the observational study the observer does not interfere with the variables or the subjects. Hence all I have to do here is just collect the opinions of the students.

Requirement B. The stratified sampling method is the method that includes the representation from every small strata (Group) which helps in assessing the complete sample because samples are extracted from each small separate group. Hence it is the best available option when the sample is the mixture of different small groups. In this case, the small groups would be first year, second year, Business student, Science student, etc.
