If an error is possible, someone will make it. The designer must assume that all possible errors will occur and design so as to minimize the chance of the error in the first place, or its effects once it gets made. Errors should be easy to detect, they should have minimal consequences, and, if possible, their effects should be reversible. — Don Norman, The Design of Everyday Things (2013)

Business Statistics II

Business Statistics II
Course number:


“All models are wrong, but some are useful”

- Statistician George E P Box in “Science and statistics,” Journal of the American Statistical Association 71:791-799

“As far as the laws of mathematics refer to reality, they are not certain; and as far as
they are certain, they do not refer to reality.”

- Einstein, Albert (1923) in Sidelights on Relativity (Geometry and Experience). P. Dutton., Co., p. 28.


This course is an exploration of writing about statistics. It will combine lecture
about new material, readings by many authors, discussions about writing, outside
writing assignments, and in-class writing exercises. Attendance and participation
will be very important each week.
