In the past, the HR department has gathered information from some management trainees, who reported the name of a competitor from which they received another offer and the size of their starting salary. The HR department thinks that these statistics may be biased and wishes to approach the whole task more systematically. Because of your expertise in marketing research practices, you have been assigned to determine the situation with respect to the last group of trainees hired.
Describe how you would select a sample of respondents to answer the question of starting salary offers. Answer from the perspective of both the company and the potential employee.
