Personality traits and job performance. Refer to the Journal of Applied Psychology (Jan. 2011) study of the determinants of task performance, Exercise 12.111

(p. 742). In addition to x1 = conscientiousness score and x2 = 51 if highly complex job, 0 if not6, 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. A matrix of correlations for all possible pairs of independent variables follows. Based on this information, do you detect a moderate or high level of multicollinearity? If so, what are your recommendations?
