Does anyone know anything about it? It's the final step of analysis that I need to take for my MRes - investigating the relationships between specific variables (to see if any groups/relationships are formed).

I've looked in my 'SPSS Survival book' and various online forums/demonstrations but I can't find it anywhere... Any advice appreciated.

Here's Andy Field's handout http://www.statisticshell.com/cluster.pdf

I did do an exam in cluster analysis at the beginning of my PhD, but I've forgotten most of it! Hopefully this handout is a good starting point.
