Data on the number of radio receiver licenses in the United Kingdom,
1927-1937 and the number of notified mental defectives per 10,000
in the United Kingdom were used by Udny Yule and Maurice Kendall in
An Introduction to the Theory of Statistics to illustrate

Tufte updated these variable with the number of letters in the first name
