   • 1972, Leonard J. Savage, The Foundations of Statistics, Dover, page 1:

     As for statistics, the foundations include, on any interpretation of which I have ever heard, the foundations of probability, as controversial a subject as one could name. As in other sciences, controversies over the foundations of statistics reflect themselves to some extent in everyday practice, nut not nearly so catastrophically as one might imagine. […] It is hard to judge, however, to what extent the relative calm of modern statistics is due to its domination by a vigorous school relatively well agreed within itself about the foundations.

   • 2004, David C. LeBlanc, Statistics: Concepts and Applications for Science, Jones and Bartlett Publishers, page 61,

     The application of statistics in the process of science can be divided into three parts: (1) obtaining data (experiment and sampling design), (2) summarizing and describing data (exploratory data analysis, descriptive statistics), and (3) using data from samples and experiments to make estimates and test competing hypotheses about the universe (inferential statistics).

   • 2012 January, Robert L. Dorit, “Rereading Darwin”, in American Scientist‎, volume 100, number 1, archived from the original on 14 November 2012, page 23:

     We live our lives in three dimensions for our threescore and ten allotted years. Yet every branch of contemporary science, from statistics to cosmology, alludes to processes that operate on scales outside of human experience: the millisecond and the nanometer, the eon and the light-year.
