Does it make sense to use the differences in p value to show a tendency or the 'importance' of the effect of a treatment. for example, I have treated a contaminated soil and I test the treatments against one control. I can see the high molecular weight contaminants are more affected by the treatment and that the p values (testing treatment against control) for these contaminants are lower than the ones of the low molecular weight ones, which if im right would mean that the significance is higher.
This seems to correlate with the graph, but could this difference in significance seen through the p values be used in itself to show the difference in the impact of the treatment, I mean in the discussion of your results.
Thank you in advance.
