To consult the statistician after an experiment is finished is often merely to ask him to conduct a post mortem examination. He can perhaps say what the experiment died of.

We can set no limit to human potentialities; all that is best in man can be bettered; it is not a question of producing a highly efficient machine, ... but of quickening all the distinctly human features, all that is best in man, all the different qualities, some obvious, some infinitely subtle, which we recognize as humanly excellent.

The analysis of variance is not a mathematical theorem, but rather a convenient method of arranging the arithmetic.

... the actual and physical conduct of an experiment must govern the statistical procedure of its interpretation.

Experimental observations are only experience carefully planned in advance, and designed to form a secure basis of new knowledge.

I believe sanity and realism can be restored to the teaching of Mathematical Statistics most easily and directly by entrusting such teaching largely to men and women who have had personal experience of research in the Natural Sciences.

Inductive inference is the only process known to us by which essentially new knowledge comes into the world.
