I have a bunch of benchmark measurements that look something like this:
sample.1 0.0000066660 0.0000062500 0.0000058330 0.0000058330
0.0000058330
sample.2 0.0000058330 0.0000058330 0.0000058330 0.0000058330
0.0000058330
sample.3 0.0000062500 0.0000062500 0.0000070830 0.0000062500
0.0000066660
i.e each measurement take on one of a set of values. The set values isn't
fixed, but they seem to go up increments; in this case, it appears to be
about 4.17e-07 (e.g. it would be impossible for a measurement to be
0.0000066440).
What is way to test for significant differences between two samples?
Sorry if this is a noob question, but I'm kinda new to this. The two tests
I'm aware of are the Student's t and Wilcoxon Rank Sum; neither seems to
apply here. I've tried Googling this, but haven't found anything useful
(maybe I'm not using the right terms...).
Any help would be greatly appreciated.
Regards,
setro
