I am looking for some help to do a principal component analysis of some data
that has 16 variables (each with a standard deviation).  I have 31 samples.
Does anyone know how to do PCA on SPSS?  This is the software I have on my
computer, but my knowledge of it is quite rudimentary.  If I can't do PCA on
SPSS, does anyone have some software that can do this analysis?  I have
tried correlation analysis (with much help from Charles Hart - thank you!),
but I don't think it really represents the data the way I would like.  I
want to see if the samples fall into groups, which is what I think PCA will
do. (I may be totally wrong)  I may need to do a cluster analysis, but I do
not no anything about this.



Any help would be greatly appreciated!



And if you are interested in forensics, you may be interested in this data.
It has to do with my cremains research.



Thank you for any thoughts,

Gretchen
