Scenario 1: A manufacturing company with 100 employees wants to conduct a survey to determine how their employees feel about existing company policies. The HR manager decides to divide the company into five clusters, Sales (18 employees), Engineering (5 employees), Production (57 employees), Maintenance (12 employees) and Management (8 employees). She then randomly chooses Sales to complete the survey and all 18 members of the Sales department are given the survey.

Scenario 2: A large multi-national company wants to survey their employees about worker satisfaction. Approximately 30% of the company workers are in the U.S., 25% are in Canada, 15% are in Australia, with 10% each in Vietnam, Panama, and Japan. Since Management believes the response may vary from country to country they decide to use a Stratified Sampling Plan, with each country representing a different stratum. They use simple random sampling to choose 100 representatives from each stratum. The survey is emailed to the selected employees and responses are requested within 30 days.
