Cool Hunter

I was watching Stuart Hunter's  What is Design of Experiments?  ( 1 ,  2 ) lectures this morning. They were made in the mid-60s for Westinghouse Electric and, after a demonstration of the exploration of a space to find the interesting location guided by a cycle of experiment, data collection and analysis, the final sentences run like this: The purpose of statistics is to analyse the data in such a way as to lead to new conjecture ... the data are expensive and the data are variable and we don't know the true response function ... All of this is part and parcel of the arts of statistics.  But they're really not very valuable unless we can call upon the experience that people such as [you, the audience] have which comes only from working in an industrial environment. And our real objective is to wed together your experience with the practical uses of engineering and production and development and research with the arts of statistics so that you will be more valuable to
