How To Compare And Interpret Output In Cluster Analysis?

#1
Good Day! I'm currently making my thesis and I'm already on the chapter of analyzing my research findings. I'm using cluster analysis specifically two-step cluster in analyzing my data. I already have the output, and was able to form three clusters. My problem for now is how do I compare and interpret the grouped data or at least identifying/determining labels of each cluster? I'm using SPSS 22 by the way.
