Research Scenario 1
A local manufacturing company is interested in determining whether employees working the day shift are as satisfied with their jobs as employees working on the night shift. The manufacturing company recruited 100 workers to rate their job satisfaction at work on a scale from 1 to 10 where 1 was not at all satisfied and 10 was extremely satisfied. The manufacturing company found that the mean satisfaction rating for day shift employees is 7.3 and the mean satisfaction rating for night shift employees is 6.1.

Research Scenario 2
The CEO of an organization read a research article describing the importance of generational influence on work motivation. He is now interested in determining if the distribution of Baby Boomer, Generation X, and Millennial employees is the same across engineering and management positions in his company. Staff in the HR department gather records and provide him with the following information:

Employee Age Group
Number of Managers
Number of Engineers

Baby Boomers
28
18
Generation X’ers
36
34
Millennials
21
45

Research Scenario 3
A training designer is interested in identifying which training technique is most effective in delivering a course on communication skills. This researcher invites 90 employees to participate in a training course, and then randomly assigns them to one of three groups—classroom lecture (n=30), programmed instruction (n=30), and blended learning (n=30). Participants in each group are trained on exactly the same information pertaining to communication skills using one of the three different delivery techniques outlined above. After the training session, employees are asked to perform in a role play activity to demonstrate their newly learned communication skills. An independent researcher (blind to training group) provides a rating of communication skills (i.e., poor “1” to excellent “5”) for each participant. The mean communication skills ratings for each group are classroom lecture (M=3.0), programmed instruction (M=2.9), blended learning (M=3.8).

Research Scenario 4
An organization has recently restructured and, in the process, has created a new department. Since the transition, members of the new department have had difficulty working with one another and departmental performance is low. An I/O consultant has been hired to implement an intervention to decrease interpersonal conflict among employees. To help diagnose the issue, he emails a survey to the 36 department members asking them to rate conflict levels on a scale from 1 (no conflict) to 10 (extremely high conflict). All 36 employees respond and the mean conflict level is 8.9. Next, he implements a 4-week conflict reduction intervention. Two weeks after the intervention is complete, he emails another survey to all 36 employees asking them to current conflict levels. All 36 employees respond and the mean cohesion level is now 4.6.
