Exercises assigned, but not graded (selected exercises may appear on tests)

Makeup tests: Makeup tests will not be given, except for legitimate scheduled university activities or grave, urgent reasons. Prior arrangements with instructor are required.

Final exam rescheduling: By Department of Statistical Science policy, no student may reschedule the final exam without permission of the Department Chair.

Outcomes: Students successfully completing this course will be able to conduct and interpret standard statistical analyses used in research, including multiple regression, analysis of variance, analysis of covariance, analysis of categorical and other non-normal data, as well as to plan sample sizes and allocations for basic designs and surveys.

The Last Will and Testament of Philip J. Klass

To UFOlogists who publicly criticize me…or who even think unkind thoughts about me in private,

I do hereby leave and bequeath THE UFO CURSE: No matter how long you live, you will never know

any more about UFOs than you know today. You will never know any more about what UFOs really

are, or where they come from. You will never know any more about what the U.S. Government really

knows about UFOs than you know today. As you lie on your own death-bed you will be as mystified

about UFOs as you are today. And you will remember this curse.

— Philip J. Klass, prominent UFO skeptic, posted on a UFO discussion site shortly before his death

Scientists on evolution, intelligent design, biblical creation:

Panda’s thumb

Why evolution is true

Dover trial transcripts (read what scientists and “cdesign proponentists” say under oath)

Department of Biological Sciences, Lehigh University

The continuing futile attacks by evolution’s opponents reminds me of another legendary confrontation,

that between Arthur and the Black Knight in the movie Monte Python and the Holy Grail. The Black

Knight, like evolution’s challengers, continues to fight even as each of his limbs is hacked off, one by

one. The “no transitional fossils” argument and the “designed genes” model have been cut clean off,

the courts have debunked the “ID is science” claim, and the nonsense here about the edge of evolution

is quickly sliced to pieces by well-established biochemistry. The knights of ID may profess these blows

are “but a scratch” or “just a flesh wound,” but the argument for design has no scientific leg to stand on.

— Sean B. Carroll, in a review (2007 Science 316:1427-1428), of Michael J. Behe’s book

The Edge of Evolution: The Search for the Limits of Darwinism.
