The mean is the "average" - the sum of the values divided by the count of the values:
31 + 28 + 30 + 31 + 30 5 = 150 5 = 30
The median is the middle value in a string of values listed from lowest to highest (or highest to lowest - they just can't be scrambled up):
28, 30, 30, 31, 31
median =30
The mode is the value that is listed most often. In this case, both the 30 and 31 are listed twice, so they are both the mode.

Refer to the Journal of Applied Psychology (Jan. 2011) study of the determinants of task performance. 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. 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? x1 x2 x3 x4 Conscientiousness (x1) Job Complexity (x2).13 Emotional Stability (x3).62.14 Organizational Citizenship (x4).24.03.24 Counterproductive Work (x5)-.23-.23-.02-.62
