2.51 Shared pain and bonding. In Exercise 2.6, you should have noticed some low outliers in the pain group. BONDING (a) Compute the mean and the median of the bonding scores for the pain group, both with and without the two smallest scores. Do they have more of an effect on the mean or the median? Explain why. (b) Does the 1.5 x IQR rule identify these two low bonding scores as suspected outliers? (c) Unusual observations are not necessarily mistakes. Suppose a small percentage of subjects would expe- ce little bonding regardless of whether they wer he no-pain or the pain group. Explain how th lomization of the students to the two group d have led to these "outliers." pain group: 3.43 4.86. 1.71 1.71 3.86 3.14 4.14 3.14 4:43 3.71 3.00 3.14 4.14 4.29 2:43 2:71 4.43 3.43 1.29 1.29 group: 3.00 3.00 2.86 2.14 4.71 1.00 3.71 4.71 4.86 4.14 1.29 2.29 4.43 3.57 4.43 3.57 3.43
