For the biologist who doubts an old hypothesis or wishes to test out a new one, there is the biological laboratory. There, under conditions over which he can exercise the most rigid control, he can vary the light, the air, the food, which his plants or his animals receive, from the moment of birth throughout their lifetime. Keeping all the conditions but one constant, he can make accurate measurement of the effect of the one. This is the ideal method of science, the method of the controlled experiment, through which all hypotheses may be submitted to a strict objective test. ... Unfortunately such methods of experiment are denied to us when our materials are humanity and the whole fabric of a social order. This is a quote from American cultural anthropologist Margaret Mead (1901-1978) from the introduction to the 1973 edition of her 1929 book "Coming of Age in Samoa: A Psychological Study of Primitive Youth for Western Civilization".
We can never achieve absolute truth but we can live hopefully by a system of calculated probabilities. The law of probability gives to natural and human sciences - to human experience as a whole - the unity of life we seek. Quote of American educator Agnes E Meyer (1887 - 1970) appearing in her book "Education for a New Morality" (MacMillan, 1957) p. 21. Also to be found in "Statistically Speaking the dictionary of quotations" compiled by Carl Gaither and Alma Cavazos-Gaither p. 131
A statistics scramble that might be used in teaching about the relationship between the mean and the median in a skewed distribution. A set of five anagrams must be solved to reveal the letters that provide the answer to the clue in the cartoon. The cartoon was drawn by British cartoonist John Landers based on an idea by Dennis Pearl. Free for use on course websites, or as an in-class, or out-of class exercise.

A set of twenty statistics anagrams that might be used for an end of semester terminology review. This collection of anagrams appeared in the article "Even More Fun Learning Stats" by Lawrence M. Lesser in issue #49 (2007) of "Stats" magazine (pp.5-8,19, 27).
The statistician who supposes that his main contribution to the planning of an experiment will involve statistical theory, finds repeatedly that he makes his most valuable contribution simply by persuading the investigator to explain why he wishes to do the experiment, by persuading him to justify the experimental treatments, and to explain why it is that the experiment, when completed, will assist him in his research. A quote from American statistician, and founder of the North Carolina State University Department of Statistics, Gertrude Cox (1900-1978). The quote is from a speech delivered at the Department of Agriculture in Washington D.C. on January 11th, 1950. The quote also appears in Chapter 1 of W.E. Deming's 1960 book "Sample Design in Business Research".
