Harold Hotelling’s review of the 1st
Ronald Fisher’s Statistical Methods for Research Workers (1925) is considered by many to be the most influential statistics book of the twentieth century. Yet according to Fisher’s biographer, “The book did not receive a single good review.” Box (1978, p. 130).
It is debateable whether Box’s generalisation applied to all the British reviews but it certainly did not apply to the review by the American statistician, Harold Hotelling. He reviewed the book on his own initiative and on the basis of it became Fisher’s earliest fan. Some spectators found Hotelling’s enthusiasm excessive. Arne Fisher, the Danish-American actuary, disapproved of “adoring disciples.” See Arne Fisher letter to RAF: correspondence p.310.
Hotelling (1895-1973) completed a PhD at
Hotelling was also a distinguished economic theorist and so it is appropriate that the National Academy of Science memoir was a joint effort from Erich Lehmann and Kenneth.Arrow, a Hotelling student and Nobel laureate in Economics.

Hotelling’s review of the 1st edition
Statistical Methods for Research Workers, by R. A. Fisher.
Most books on statistics consist of pedagogic rehashes of identical material. This comfortably orthodox subject matter is absent from the volume under review, which summarizes for the non-mathematical reader the author's independent codification of statistical theory and some of his brilliant contributions to the subject, not all of which have previously been published.
The theory of probable errors in ordinary use is valid only in the limit as the size of the sample approaches infinity. The author has created most of the existing theory of small samples. It is therefore natural that the book deals largely with methods which must be used where the number of cases is limited and which, he holds, may well be used in general. Common occurrence in economic and other statistics of short series will make the work valuable to a larger class of research workers than the biologists for whom it was primarily intended.
Of particular interest are the methods of evaluating the significance of correlation coefficients drawn from small samples, the tests of significance of differences of means, and the method (p. 125) of fitting a polynomial to a series of observations by adding terms one at a time until the fit is sufficiently good. All these are due entirely, I think, to Mr. Fisher's own researches. Some of the tables, particularly V (A) which gives the values which a correlation coefficient must attain in order to reach certain levels of significance, are indispensable for the worker with moderate-sized samples.
The author (who must not be confused with Arne or Irving Fisher) has an answer to the query as to the singular of “statistics.” A statistic is a quantity such as an average or correlation coefficient which summarizes characteristics of a body of data relevant to a particular inquiry. The criterion of “maximum likelihood” for the derivation of statistics which he invented is illustrated. His position regarding the number of classes with which tables of χ2 must be entered is clearly set forth.
Some slight preliminary knowledge of statistical concepts is needed to make the reading smooth. The absence of proofs and the omission of some topics make the book inadequate for mathematical readers, who will find it desirable to read also the author's original papers. If used in a course in mathematical statistics it should be supplemented with these proofs. It would be impossible to combine in such brevity a compendium of sound practical methods with a complete theoretical development. The author's work is of revolutionary importance and should be far better known in this country.
