Company A has 500 employees. Company B has 800 employees. Would the analyst working with company B need to interview more employees than the analyst working with Company A? Why or why not?
What will be an ideal response?
An analyst does not have to interview more people just because they are working with the larger organization. If the stratified sample is done properly, a small number of people will adequately represent the entire organization.
