以下是一个实验方法学的问题,根据以下这个例子回答下边提出的问题:

Industrial psychologists were interested in effects of goal-setting strategies on work productivity. Fifty subjects participated in this six-momth study. All subjects were in middle management positions in computer-oriented firms. Subjects were randomly assigned. Group 1 received training on goal setting. Subjiects in Group 1 were asked to keep daily written logs of work goals and checklists of goals accomplished. Supervisors were asked to verify the checklists of goals accomplished on a weekly basis and to present specific personal feedback. Group 2 received no goal-stting training. Group 2 met with their supervisors weekly in regularly scheduled general staff meetings and discussed work-related problems. Supervisors were asked to document the work accomplishments of the subject weekly. Work productivity was rated by both the subjects and their supervisors at the end of six-month study.
