Hello, I collected sequences along an environmental O2 gradient and I want to look at how alpha diversity metrics change as a function of O2 concentration.
For example, I used the alpha-correlation method to generate this plot of Faith PD vs. O2:
alpha_correlation_faith_pd_O2_metadata.tsv (3.0 KB)
faith-pd-correlation_PAL.qzv (386.6 KB)
The plot makes sense to me, but I do not understand how to interpret the calculated Spearman values (Test Statistic = 0.5164; P-Value = 0.0011). Could someone please explain to me what these values mean in this instance? Or maybe someone could link a reference or previous post that explains how to read these values?
