Hi, I'm sorry if there has been similar posts previously, but I haven't been able to find them.
I've compared 6 different sampling methods (on the same subjects) and get the following mean pd_wholetree metrics:
group 1: 35.9
group 2: 30.6
group 3: 29.9
group 4: 27.6
group 5: 26.2
group 6: 22.2
All comparisons between groups (paired t-tests and non-parametric paired signed rank test) are highly significant as well as a non-parametric test for an ordered trend.
However, could somebody tell me how to know wether these rather small numerical differences (at least for groups 2-5) bear any biological meaning?
