Solved – Fisher’s exact test and Bonferroni correction

Question

I compared Survivability (live or die) using tibial Intraosseous (io), humerus io, tibial io, intravenous epinephrine for patients who have cardiac arrest. We had a control group that received no drug. Do I need to do a Bonferroni correction? .05/5.?

Answer 1

You could use that bonferroni correction but your p-values are correlated. Bonferroni applies regardless as a control on the familywide error rate but the procedure could have poor power (be overly conservative).
