Peter Farley's lament is understandable, but it is important to
[better] understand that all scientific and engineering questions are
statistical in character and that they become so increasingly as a
subject advances.

Deterministic, Newtonian methods served physics well in the 17th
century; but the question is there or is there not a Higgs Boson must
be and is being addressed statistically. (The tentative answer is yes.)

Performance measurement has reached this stage.  Non-statistical
questions only mislead; such measurements are experiments that
must be designed explicitly and in advance.  As Sir Ronald Fisher put
the matter

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