darwin[edit]

I have the Darwin family tree done in PowerPoint. Please post on my talk page to request changes or email me to get a copy of the PowerPoint.Cutler 21:21, 3 Mar 2004 (UTC)

In my editing on 3 Jun 2005, 17:34, I'm pretty sure I did not inadvertantly take out anything already on the article. I'm sure it's all there, but some things may be disputed.--AI 03:41, 4 Jun 2005 (UTC)


Histerionics[edit]

What does word refer to? Is it a misspelling of "histrionics"? Does it refer to "historiometry"? Would a different word be better? -Willmcw 23:43, August 11, 2005 (UTC)


cardiogram[edit]

Galton did not invent the electrocardiogram as someone claimed. I have removed this. —The preceding unsigned comment was added by Gavantredoux (talkcontribs) 18:13, August 20, 2007 (UTC).

Correction: Origins of correlation[edit]

The section "Correlation and regression" currently begins: "After examining forearm and height measurements, Galton introduced the concept of correlation in 1888 (Bulmer 2003, pp. 191–196). Correlation is the term used by Aristotle in his studies of animal classification, and later and most notably by Georges Cuvier in Histoire des progrès des sciences naturelles depuis 1789 jusqu'à ce jour (5 volumes, 1826–1836). Correlation originated in the study of correspondence as described in the study of morphology. See Edward Stuart Russell, Form and Function (1916)."

I have read the relevant sections of Russell's book. First, Aristotle did not use the term "correlation"; rather, he noted what later biologists would term "correlations". These were not statistical correlations; rather, they were similarities between corresponding parts of different animals, which Aristotle studied in an attempt to trace the evolution of animals. The same objection applies to Georges Cuvier's work.

The formulation of a correlation coefficient began with Auguste Bravais (1811-1863) in his paper of 1846, "Analyse mathematique sur les probabilites des erreurs de situation d'un point" (Mathematical analysis of the probabilities of a point's location). In 1888, Francis Galton independently developed a similar measure of correlation.

Therefore, I have deleted the material about Aristotle and Cuvier, and replaced it with material about Bravais. Cwkmail (talk) 20:42, 24 February 2014 (UTC)

Spelling[edit]
