Juliet Popper Shaffer (born May 23, 1932) is an American psychologist, statistician and statistics educator known for her research on multiple hypothesis testing.
At Kansas, Popper was involved with local struggles for desegregation, and became the first chair of the university's Affirmative Action Board.
The psychology department there was not hiring, so she took a visiting position at the University of California, Davis and then a year later became a lecturer in statistics at Berkeley.
At Berkeley, she also ran a "drop-in consulting service", and by 1981 achieved security of employment, the equivalent of tenure for lecturers.
[3] She is also a fellow of the American Association for the Advancement of Science and an elected member of the International Statistical Institute.
[1][3] In 2003, the Committee of Presidents of Statistical Societies gave her their Florence Nightingale David Award "for her pioneering contributions to statistical methods in education and psychometrics; for her exceptional role in fostering opportunities for and in support of the advancement of women in the sciences".
