Subject:      Data entry for Hierarchical Clustering
Content-Type: text/plain; charset=us-ascii

I have done a cardsort with 40 cards and 65 subjects. For analyses I
want to perform MDS and hierarchical clustering. Currently my data are
in the form of the lower half of a 40x40 symetrical similarities matrix.
To create a dissimilarities matrix, can I simply subtract the number of
matches for each pair of cards from the total possible (65)? When I do
this, the MDS solution seems to make sense, but the hierarchical
clustering doesn't. Can anyone point me in the right direction?
