Question

suppose you want to determine the mean number of cans of soda drunk each month by students in their twenties at your school. Describe a possible sampling method in three to five complete sentences.

Answer 1

There can be multiple sampling methods that can be used to model this particular scenario.

One of these which can be used to determine the mean number of cans of soda drunk each month by students in their twenties at your school is a systematic sampling method. In this particular type of sampling method, the members from a comparatively large population are selected according to a random starting point but with a fixed, periodic interval. The data collection method would be something like this: Stop every seventh person as they leave the library which is located on the campus early morning, say around 9 AM. Then stop every fifth person who leaves the cafeteria around lunch hours i.e. around 2 PM. Then again stop every seventh person who leaves their dorm room at night say around 7 PM. This way a systematic sample can be collected at different parts of the campus and at a fixed periodic interval.
