Third Quarter Group Project: Controlled Experiment

Group #, leader, other members	Summary (Short Title)	Outcome	Significance tests and P-values (to be computed independently by pairs working on project due 4/5/2001)
1. David Pachner, Tad Bardenwerper, Sam Goldberg, François Rodamar	Can a randomly selected STA student distinguish Sam’s Bar doughnuts from Maple doughnuts sold at Giant Food?	Yes, with the number of weekly doughnuts purchased at Sam’s having a strong influence on the subject’s ability to tell the difference.
2. Paul Parmley, Michael Matthews, Arthur Peterson, Jon Shearin	Will the Pure Shot shooting device improve basketball shooting percentage?	No, at least not in the short term.
3. Marc Peñalver-Aguila, Nate Guggenheim, Jake Lau, Brian Rabbitt	Can STA students distinguish between potato chips of varying price?	Not very well. Researchers speculated that the results were not much better than those that would have been obtained by random guessing.
4. Nik Raman, Yoon Cho, Fareed Melhem, Colin Zima	Does ink color affect reading speed?	Yes; passages in black ink take less time to read, on average, than passages in red ink.
5. Robby Andreoli, Chris Eby, Claire DeBord, Portia Mills	Can STA students tell the difference between red and green ketchup?	Possibly, but this ability does not appear to be statistically significant.
6. Josh Holland, Ed Ferrer, Rob Gillette, Will Rawson	Does time affect memory?	Yes, with a slight fall-off after 2 minutes, slightly more after 5 minutes, and noticeably more after 10 minutes.
7. Michael McCullough, David Waikart, Will Wilkins, Camille Green	Cell telephones and their effect on driver distraction	Video-game simulation (Nintendo 64 Beetle Racing Adventure) suggests that cell phone usage causes a dangerous amount of driver distraction.
8. Simon Quint, Ruben Harutunian, John Martin, Sam Mock	Which pen writes better?	In a carefully blinded test (note: original methodology said double-blind, but the final project report was unclear on this point), STA students clearly preferred the writing of the more expensive of two pens, by a margin of 25 to 10.
