The Tendency Of Modern Scientific Teaching Is

The Analysis Of Variance Is Not A Mathematical Theorem, But Rather A Convenient Method Of Arranging The Arithmetic.

If One In Twenty Does Not Seem High Enough Odds, We May, If We Prefer It, Draw The Line At One In Fifty (the 2 Per Cent. Point), Or One In A Hundred (the 1 Per Cent. Point). Personally, The Writer Prefers To Set A Low Standard Of Significance At The 5 Per Cent. Point, And Ignore Entirely All Results Which Fail To Reach This Level. A Scientific Fact Should Be Regarded As Experimentally Established Only If A Properly Designed Experiment Rarely Fails To Give This Level Of Significance.

... The Actual And Physical Conduct Of An Experiment Must Govern The Statistical Procedure Of Its Interpretation.

The So-called Co-efficient Of Heritability, Which I Regard As One Of Those Unfortunate Short-cuts, Which Have Often Emerged In Biometry For Lack Of A More Thorough Analysis Of The Data.

It Was Darwin's Chief Contribution, Not Only To Biology But To The Whole Of Natural Science, To Have Brought To Light A Process By Which Contingencies A Priori Improbable, Are Given, In The Process Of Time, An Increasing Probability, Until It Is Their Non-occurrence Rather Than Their Occurrence Which Becomes Highly Improbable.
