WebJSTOR Home WebJul 6, 2024 · Fisher’s most distinctive contribution to significance testing was that contained in the shift from large-sample to small-sample methods, and it was this shift that made the new theory specifically a theory of statistical inference. Yule (1911) give some indication how the switch came about.

WebSignificance tests or hypothesis tests It is often considered important in discussing P-values to make a clear distinction between the Fisherian test of significance and Neyman–Pearson hypothesis testing. However, operationally at least, this distinction is less important than is sometimes supposed. WebWith Fisherian significance tests a single model is tested, and if rejected one of many plausible alternatives is inferred.

WebFisher (1955, p. 74) complained, justifiably, that his significance test had become “assimilated” into the N–P hypothesis testing framework.
