 Use the data attached to tackle the “Oh, James” case study at the end of  chapter 9 page 362 (Attached).  

1. Despite potential objections regarding the  sample size, which clustering variables would you choose in light of the  study objective (Single linkage, Complete linkage, Average linkage, or Centroid), their levels of measurement, and correlations?  

2. Given the levels of measurement, which clustering method do you prefer?  

3.Finally, carry out a cluster analysis w/ an emphasis on the interpretation of results.
