I am a beginner in R and statistics.
I conducted Chi-square test to see if there is a significant difference/relationship between two distributions.
Then, I changed my units to percentage over total counts instead of absolute counts. So previously, my counts were in their thousands, but now, percentage counts are in decimal places(like 0.2%) and 30% at max.
Is it normal for chi-square to not work? (I am aware that in order to use chi-square test, frequency should be over 5)
So instead of Chi-square test, I tried to use Fisher's exact test, but now they give me p-values that are insignificant.
Do you suggest there's an error in my codes or can this happen? Do you suggest other statistical tests?
