Solution to question on a study of back pain and heart disease, 5

We could use the Bonferroni method. This would require us to calcuate the number of relevant tests done, here at least 16. We would then multiply the P values by this. If any is P value is then below 0.05, the relationship is significant. If our initial hypothesis were specifically about ischaemic heart disease, we would have four tests only, and the relationship between IHD and back pain in younger men would have P= 4 times 0.02 = 0.08, not significant ( Intro 9.10).

Back to question.
