Extract

Testing the null hypothesis has been the cornerstone of much statistical theory and practice over the last few decades. During this time it has encroached on most disciplines and become widespread in use within them. There are now few research papers in the scientific literature where the outcome of one or more hypothesis tests is not reported. With this ‘progress' there has undoubtedly been an improvement in the way in which data have been collected, analysed, and interpreted, and a move towards more objective evaluation of study results.
