What is it about?
In 1931 WS Gosset ("Student") offered his own analysis of The Lanarkshire Milk Experiment (LME) of 1931. The original analysis by Leighton and McKinlay and Student's reanalysis are considered from a more modern perspective and various lessons for the design and analysis of experiments are drawn.

Why is it important?
At the time of Student's analysis the modern theory of design of experiments as initiated by RA Fisher and continued by his successor at Rothamsted, Frank Yates, had not been fully developed. The LME is of a form that was subsequently referred to as 'an incomplete blocks design', with treatments varied both within and between schools. The implications of this for analysis are examined using this more modern perspective.
