Would it be useful to voice your dilemma to your advisor? Something like:

When I hear your request, I am hearing you ask me to fudge the numbers so that this experiment has a more desirable outcome. Is that really what you want me to do? If not can you help me understand how to achieve what you are asking?

Also even if you can’t ask your advisor, maybe there is someone else with authority you could ask
