The statistical techniques reported in medical journals are often poor
ly understood and misused by researchers, and difficult for readers to
comprehend. Even the relatively simple t test embodies an intricate c
ollection of mathematical formulas such as the Normal approximation, w
ith unintuitive elements such as pi and e. The researcher must consult
a body of rules indicating whether a technique is applicable or inapp
licable. If he or she does select a sound method and use it correctly,
its mathematical complexity will still leave most readers in the dark
. In most situations the resampling approach is at Least as efficient
as the formulaic method. It is transparently clear to the researcher a
nd reader, and it protects the researcher from using the wrong formula
ic technique. In this paper we will define the four steps in the resam
pling method, compare this procedure with standard formulaic treatment
of the same data, and discuss the advantages of the resampling approa
