A management consultant was interested in gauging the success of different motivation-enhancing practices on employees. She had three groups of employees who underwent different types of practices: a group team-building exercise, a confidence-building meeting and the promise of performance-related pay. After the motivational practice, participants were asked to endorse nine statements relating to their motivation (on a five-point Likert scale from 1 = disagree to 5 = agree): (1) I live for succeeding in my job, (2) I look forward to work when I get up in the morning, (3) I do not like missing days through illness, (4) I want to work hard to gain promotion, (5) I am going to be more successful this year than last, (6) I am in this job to pay the bills, (7) People who work harder than
me irritate me, (8) I often look on the internet for other jobs, (9) I can’t be bothered with work. What analysis should be employed to ascertain whether the three motivational practices had an effect on responses to these nine items? A. Factor analysis B. MANOVA C. Repeated-measures ANOVA D. Mixed ANOVA
