Hi, this might sound trivial, but I'm pretty new to R and statistics in general. What I want to do is to compare two data values. The hook is, that they are non-normally distributed and that one value is five times as big as the other. The box-plots look like this <http://r.789695.n4.nabble.com/file/n4678190/mixture_vs_monoculture.png> . Ignore the number at the bottom. I want to know if those two are significantly different from one another. I tried it with the wilcox-test (because it is advertised as a non-parametric test), but get a p-value of 0.0009 and naturally don't quite believe it to be true. Do you have any suggestions how I can handle that problem?
