I am having trouble figuring out the correction factor to choose for a Bonferroni correction. Let me explain.
I have two datasets, control ($x$) and data from left ($y_1$, affected limb) and right limb ($y_2$, non-affected limb) of a pathology group. As $y_1$ and $y_2$ were from the same subject (paired data), I have performed a Wilcoxon signed-rank test to compare if these data were statistically different.
However, when I compared the data between $x$ and $y_1$ or, between $x$ and $y_2$, I used a Wilcoxon Rank-Sum Test.
As there are multiple tests, should I use correction factor of 3 ($p<=\frac{0.05}{3}$)?
Or ($p<=\frac{0.05}{2}$) for group ($x$ and $y_1$) and ($x$ and $y_2$) only and no correction for group ($y_1$ and $y_2$)?
I would really appreciate your kind reply. Thank you.
