Hi,
I have a dataset with samples measured after incubation for 0, 1 and 2 days.
Each sample was prepared in triplicates, and each replicate was then incubated at 0, 1 or 2 days.
I'm interested in testing if the incubation time had any affect on the measurements.
Which test would be correct to use? Is it a paired test (matched pairs) or unpaired? The data is non-parametric.
Thanks.
