Ronald Fisher
Sir Ronald Aylmer Fisher FRS, who published as R. A. Fisher, was an English statistician, and biologist, who used mathematics to combine Mendelian genetics and natural selection, helping to create a new Darwinist synthesis of evolution known as modern evolutionary synthesis, as well as a prominent eugenicist in the early part of his life...

died english-mathematician perform
To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.
examination experiments died
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.
programming adapted organisms
The more highly adapted an organism becomes, the less adaptable it is to any new change.
independent data expectations
Although no explanation can be expected to be satisfactory, it remains a possibility among others that Mendel was deceived by some assistant who knew too well what was expected. This possibility is supported by independent evidence that the data of most, if not all, of the experiments have been falsified so as to agree closely with Mendel's expectations.
credulity
Faith Is Not Credulity.
order giving null
(Coining phrase "null hypothesis") In relation to any experiment we may speak of this hypothesis as the "null hypothesis," and it should be noted that the null hypothesis is never proved or established, but is possibly disproved, in the course of experimentation. Every experiment may be said to exist only in order to give the facts a chance of disproving the null hypothesis.
statistics causes steps
If ... we choose a group of social phenomena with no antecedent knowledge of the causation or absence of causation among them, then the calculation of correlation coefficients, total or partial, will not advance us a step toward evaluating the importance of the causes at work.
science men thinking
The statistician cannot excuse himself from the duty of getting his head clear on the principles of scientific inference, but equally no other thinking man can avoid a like obligation.
statistics degrees natural
Natural selection is a mechanism for generating an exceedingly high degree of improbability.
science support intellectual
The best causes tend to attract to their support the worst arguments, which seems to be equally true in the intellectual and in the moral sense.
done plans experiments
The best time to plan an experiment is after you've done it.
evolution natural natural-selection
Natural selection is not evolution.
knowledge world inference
Inductive inference is the only process known to us by which essentially new knowledge comes into the world.
variation experiments related
We have usually no knowledge that any one factor will exert its effects independently of all others that can be varied, or that its effects are particularly simply related to variations in these other factors.
