I know this will vary from journal to journal, but I'm working on my first publication and have had little guidance, so any personal experiences would be helpful to me.
When you present your p-values for highly significant data, where do you stop? For example, I have some p-values that are equal to 7 * 10^(-14) (or 7E-14, or 0.00000000000007). In this situation, where do you make the cut-off? Would you just say p < 0.00001? If so, an additional question arises - if I have two tests that are highly significant but are different from each other, say one has p = 2*10^(-10) and the other is p = 5*10^(-30), are they both reported as p < 0.0001 (or whatever the cut-off is)? Does it matter that one is so much smaller (and therefore more significant) than the other?
