As a research psychologist you conduct a study that examines the effect of offering a benefits package on job satisfaction. In this study a group of new employees is offered a benefits package; another group is not. Which is the control group?

the group not receiving the benefits package

Explanation:

A control group in a scientific experiment is a distinct group from the rest of those involved in  experiment and where the testing of the independent variable can not influence the results of the experiment. It separates the results on the experiment from the independent variable and may help to find out alternative explanations of the experimental results. As per the question,  employees who have not offered a benefits package would not influence the experiment and therefore should be called controlled groups.
