In sample size calculations, where do we use absolute and relative precision? Is relative precision indicated where the population size is finite and known to us and vice versa?
Yamane (1967) Formula is best
I would also propose to check Eng (2003) for sample size estimation.
Instead of checking only the mRNA level, I want to check the active protein level of MMP-1 in Liver tissue from mice. How can I do that?
