Bit of a stats question here. I have lots of samples from which I've measured lots of things. I'm wondering, is there some way I can probe the data for correlations between these things, for instance between levels of one chemical and another, or pH with potassium content?

Obviously, I don't want to have to test every single permuation separately, manually.

Would the Pearson's correlation coefficient (I think you need normal data for that) using SPSS be useful? I do not know much about statistics, but I have used it to test for correlations. If you have all the data in SPSS, it just gives you a table with a cross matrix automatically. Not sure if this is what you are looking for though.
