hello
i am trying to decipher a dendrogram i have from performing a 'tree'. (attached file) my response variable is factored - low, medium and high threat and the 8 explanatory variables are numeric values.  

i could do with some help to understand what the values <0.25, <0.5 and <0.75 are on the tree branches? how does one interpret this???  

cheers,
mann
