A manager at a large company wants to understand whether the employees are feeling overworked while completing a project. The company has 200 employees working on the project all over the world, but the manager only has time
and money to collect information from 50 people.
For this situation, which would be the best way to collect data-an experiment, a survey, or another type of
observational study? Explain your reasoning.
Describe a good method that the manager could use to select the 50 people for the study. Why is your proposed
method better than collecting information from the 50 people working on the project at a particular location?
