Abstract
UNDER this heading, G. A. Barnard1 puts forward a test which, in language adopted from Neyman and Pearson, "is more powerful than Fisher's". This means in practice that the test advocated passes as significant certain classes of experimental result which, by the test I had put forward2, would have been judged insignificant; and that, as judged by Barnard's method, my test is thought to be too stringent. However one may choose to express it, the cause of the difference in these calculations is worth elucidating, and, in taking the view he does, Barnard is following the very distinguished precedent of Prof. E. B. Wilson, whose similar proposal a few years ago3 led to some clarification of the issue4, 5, 6.
