Statistical Methods for Research Workers

to be one of the 20th century's most influential books on statistical methods, together with his The Design of Experiments (1935).

His Design of Experiments (1935) [promoted] statistical technique and application.

In that book he emphasized examples and how to design experiments systematically from a statistical point of view.

The mathematical justification of the methods described was not stressed and, indeed, proofs were often barely sketched or omitted altogether ..., a fact which led H. B. Mann to fill the gaps with a rigorous mathematical treatment in his well-known treatise, Mann (1949).

"[2] In the second edition of 1928 a chapter 9 was added: The Principles of Statistical Estimation.
