you nervous when you see NCWEE? concerned when you see CIRC? perturbed when you
see PBC? Visit Mr. Hansen’s fabled abbreviations

find a complete college statistics course (complete with clickable glossary and great
case studies), simulations, and some excellent analysis tools.

so that it returns the LSRL equation at the end (follow-on to a stat teacher
workshop I attended on 12/5/2001)

Philosophical Links:
-- In praise of Bayes: a very readable overview of the tension between
the standard (“frequentist”) approach to probability
and the Bayesian view
Controversial Links:
-- Does an elite
college really pay? Article addresses the issue of whether you would do
better financially if you simply invested the difference in tuition price.
-- Does
traditional hypothesis testing actually make sense? Article questions
whether the entire second semester of our course is a waste of time . . .
-- Are
law schools cooking their ranking statistics? Every high school statistics
student should read this (and maybe a second time, four years later).
