The Design of Experiments

The Design of Experiments is a 1935 book by the English statistician, Ronald Fisher, on experimental design, considered to be a foundational work in modern statistics and experimental methodology. The book introduced concepts such as randomization, replication, blocking, and contains Fisher’s influential discussion of the null hypothesis, illustrated in the context of the Lady tasting tea experiment. The book has had a lasting impact on the development of statistical science, shaping diverse fields such as agriculture, psychology, and medical research. It remains an important reference in the history of applied statistics and the philosophy of scientific testing.
