Personality traits and job performance. Refer to the Journal of Applied Psychology (January 2011) study of the determinants of task performance, Exercise 12.94 (p. 770). In addition to x1 = conscientiousness score and x2 = {1 if highly complex job, 0 if not}, the researchers also used x3 = emotional stability score, x4 = organizational citizenship behavior score, and x5 = counterproductive work behavior score to model y = task performance score. One of their concerns is the level of multicollinearity in the data. Below is a matrix of correlations for all possible pairs of independent variables. Based on this information, do you detect a moderate or high level of multicollinearity? If so, what are your recommendations? x1 x2 x3 x4 Conscientiousness 1x12 Job complexity 1x22 .13 Emotional stability 1x32 .62 .14 Organizational citizenship 1x42 .24 .03 .24 Counterproductive work 1x52 -.23 -.02 -.25 -.62
