Most importantly, exploratory data can help to guide an a-priori power-analysis for a following hypothesis-driven experiment when no good reference data are available. For example a p value of 0.04 tells us that if a null hypothesis of no difference is true, the probability of falsely rejecting it is less than 5% (type-I error).13The typ-ical value of β is set at 0.2 (relates to 80% power). An a priori assumption may be brought out in a legal complaint, motion, or even at trial, as one party’s line of reasoning stems from something that has happened in the past. 20 Equivalence and noninferiority trials usually require larger sample sizes.
