The Design of Experiments is a 1935 book by the English statistician Ronald Fisher about the design of experiments and is considered a foundational work in experimental design. [1] [2] [3] Among other contributions, the book introduced the concept of the null hypothesis in the context of the lady tasting tea experiment. [4]
Fisher held strong views on race and eugenics, insisting on racial differences. Although he was clearly a eugenicist, there is some debate as to whether Fisher supported scientific racism (see Ronald Fisher § Views on race). He was the Galton Professor of Eugenics at University College London and editor of the Annals of Eugenics. [34]
The experiment asked whether a taster could tell if the milk was added before the brewed tea, when preparing a cup of tea. Ronald Fisher in 1913. In the design of experiments in statistics, the lady tasting tea is a randomized experiment devised by Ronald Fisher and reported in his book The Design of Experiments (1935). [1]

The variance of the estimate X 1 of θ 1 is σ 2 if we use the first experiment. But if we use the second experiment, the variance of the estimate given above is σ 2 /8. Thus the second experiment gives us 8 times as much precision for the estimate of a single item, and estimates all items simultaneously, with the same precision.
Ronald Fisher. Statistical Methods for Research Workers is a classic book on statistics, written by the statistician R. A. Fisher.It is considered by some [who?] to be one of the 20th century's most influential books on statistical methods, together with his The Design of Experiments (1935).
However, when applied to data from non-randomized experiments or observational studies, model-based analysis lacks the warrant of randomization. [29] For observational data, the derivation of confidence intervals must use subjective models, as emphasized by Ronald Fisher and his followers. In practice, the estimates of treatment-effects from ...
[1] [2] The title comes from the "lady tasting tea", an example from the famous book, The Design of Experiments, by Ronald A. Fisher. Regarding Fisher's example, the statistician Debabrata Basu wrote that "the famous case of the 'lady tasting tea'" was "one of the two supporting pillars [...] of the randomization analysis of experimental data".
