ABSTRACT
For these scores, the mean is 10.0. (Since the scores sum to 70 and there are 7 scores, 70/7 = 1 0.0). Now, if we subtract the mean from each score, we have what are called the deviation scores, which indicate the number of points that each score differs from the mean. The symbol for the deviation scores is a lower case x, to differentiate it from the scores
