Extrа Credit: In оrder tо receive full credit, pleаse cоmpletely аnswer the following (3 points total): A researcher was interested in determining whether more frequent breaks (i.e., "coffee breaks") in a business setting would help employees to be more productive. With the cooperation of the management, employees on one floor of the corporate offices were allowed to take a 10-minute break each hour (at any time) between 8 and 11 a.m. (for a total of 30 minutes). The comparison group comprised of employees on different floors who followed the usual corporate policy of taking a 30-minute break sometime during the morning (at any time). Measures of productivity were gathered for each employee according to his or her job (e.g., number of reports written, number of sales made). Productivity was compared between the groups once a month for six months before and six months after the intervention started in July. Quite surprisingly, the productivity of both groups increased following the onset of the intervention, suggesting to the researcher that the timing of breaks makes no difference. (a.) What type of research design was used in this study? (Be specific; 0.5 points) (b.) Explain why the "Hawthorne effect" might have influenced the results of this study. (1 point) (c.) Describe two threats to internal validity that might be present in this study due to the way the researcher implemented it. (List and tell why each threat might be present to receive full credit; 1.5 points)
