Answer: A.Select different numbers of sales people as your independent variable and changes in sales of health care servers, as the dependent variable
Explanation:
Here is the complete question:
As marketing vice president of Health Care Services, Inc., you are in charge of developing an experiment to test the hypothesis that increasing the number of salespeople assigned to a territory will increase sales of health care services in the territory. Which experiment will do this best?
A.Select different numbers of sales people as your independent variable and changes in sales of health care servers, as the dependent variable.
B. Select three degrees of service health care (poor, good, average) as your independent variable and measure customer responses for each grade using the same number of sales representatives in each territory as your dependent variable.
C. Create an incentive program for your sales force based upon individual performance. Use increases in customer satisfaction as your independent variable and increases in sales performance as your dependent variable.
D. Create an incentive program for our sales force based upon individual performance. Use increases in customer satisfaction as your dependent variable, and increases in sales performance as your independent variable.
E. Create an incentive program for your sales force based upon team performance. Use increases in customer satisfaction as your independent variable and increases in sales performance as your dependent
variable
From the question, the vice president wants to test the hypothesis that an increase in the number of salespeople that are assigned to a territory will also increase the sales of health care services in the territory.
The interest is on whether changing one of the independent variables leads to a change in the behavior of its dependent variable which is studied. Increase in the number of the salespeople that are assigned to a territory is the causal condition which is the independent variable while the change in sales is the dependent variable. The problem was based upon the number of sales representatives, and not upon the sales performance, therefore options b, c, d, and e are not correct.
