John Tukey

Encyclopedia : J : JO : JOH : John Tukey


John Wilder Tukey (June 16, 1915 - July 26, 2000) was a statistician born in New Bedford, Massachusetts.

Tukey obtained a Bachelor of Science degree in 1936 and a Master of Science degree in chemistry in 1937 from Brown University before moving to Princeton University to study for his doctorate in mathematics. During World War II, Tukey worked at the Fire Control Research Office and collaborated with Samuel Wilks and William Cochran. After the war, he returned to Princeton, dividing his time between the university and AT&T Bell Laboratories.

His statistical interests were many and varied. He is particularly remembered for his development with James Cooley of the Cooley-Tukey Fast Fourier transform algorithm. In 1970, he contributed significantly to what is today known as the jackknife estimation - also termed Quenouille-Tukey jackknife. He introduced the box plot in his 1977 book, Exploratory Data Analysis.

He also contributed to statistical practice and articulated the important distinction between exploratory data analysis and confirmatory data analysis, believing that much statistical methodology placed too great an emphasis on the latter. Though he believed in the utility of separating the two types of analysis, he pointed out that sometimes, especially in natural science, this was problematic and termed such situations uncomfortable science.

He wrote four papers with his fifth cousin Paul Tukey, who was an undergraduate at Princeton when they met.

Among many contributions to civil society, Tukey served on a committee of the American Statistical Association that produced a report challenging the conclusions of the Kinsey Report, Statistical Problems of the Kinsey Report on Sexual Behavior in the Human Male.

Tukey coined many statistical terms that have become part of common usage, but the two most famous coinages attributed to him were related to computer science. While working with John von Neumann on early computer designs, Tukey introduced the word "bit" as a contraction of binary digit. Tukey used the term "software" in a computing context in a 1958 article and this may have been the first published use.

A D Gordon offered the following summary of Tukey's principles for statistical practice:

Retiring in 1985, Tukey died in New Brunswick, New Jersey in 2000.
