What value should I present if there is no correlational relationship?

I am happy to answer.

Thank you.

Maybe you should clarify what you mean by “no correlation.” If you mean no linear correlation between two variables, say A and B, the Pearson correlation coefficient should be zero (r=0). However, you should pay attention that no linear correlation doesn’t mean there are no non-linear associations between A and B. If you mean no linear or non-linear relationship between A and B, then you may want to say that A is independent of B (AꓕB).
