The answer to that question depends to some degree on the nature of your data and who your audience(s) are.

What constitutes a case? I.e., what are the distances between?

What are the dimensions (variables usually) that went into the distances?  What were they? How were they chosen? How many are they?

Why did you choose Euclidean distance?  Is there a reason to assume that the dimensions are pretty much uncorrelated?

Do you expect to find a tree structure? Or are you looking to construct a single nominal level variable whose levels are the clusters?

Hi all,  

I have a table of Euclidean Distances for 100 cases (a 100 x 100 table) which I computed using PROXIMITIES. I am looking to present this data visually to identify any clusters of cases that represent groups of similar cases.  

Is there a preferred method of presenting a visual map of this data that can be implemented with SPSS 20?  

Thanks,

Adam Troy
