In the development of classical statistics in the second quarter of the 20th century two competing models of inductive statistical testing were developed. Their relative merits were hotly debated (for over 25 years) until Fisher's death. While a hybrid of the two methods is widely taught and used, the philosophical questions raised in the debate have not been resolved. Fisher popularized significance testing, primarily in two popular and highly influential books.
