Outcome

Jake Williams, Chris Hayes, Mr. Hansen

Presidential impeachment opinion survey (by special permission)

Deliberately slanted wording of impeachment question appears not to matter. Students on the whole were equally divided as to "Y" or "N," with most following party lines. Study also found other STA-wide trends in factual data.

Norman Summers, Karim Sarr, Bob Jeffrey

GPA vs. sleep

No correlation found between GPA and amount of time spent sleeping.

Evan Oremland, Dan Spring, Stephan Hein

GPA vs. TV

No correlation found between GPA and amount of time spent watching TV.

Alex Kapur, Shaka Caldwell, Jimmy Carr

Sleep vs. age

Strong negative linear correlation (in mean trace) seen between sleep and age; same is true of sleep vs. form, as well as sleep vs. class load.

Sam Bond, Chris Muller, Dan Healey

AP vs. college prestige

Mean and median traces show moderate positive linear correlation between number of AP courses taken and the prestige (as measured by USN&WR ranking) of the colleges to which seniors applied.

Garth Hogan, Jamey Harding, Corey Aber

Hockey salaries vs. performance

Hockey is harder than other sports for associating salary with point-based performance metrics. Log-linear correlation is positive but weak.

Kamal Aqui, Brian Barrett, Brandon Dixon

Olympic medals vs. population

Weak positive linear correlation found between medals won at 1996 Summer Olympics and population sizes of competing countries. Lurking variables (location, GDP, etc.) probably explain why the correlation is not stronger.

Will Felder, Eric Love, Dan Creighton

Varsity athletes’ measurements

Chest size and thigh size show moderately strong positive linear correlation in separate clusters for football, soccer, and cross-country.

Trevor Winstead, Willy Rasmussen, Tyler Morrison

Commute time vs. distance from school

Strong nonlinear correlation found, modeled by a curve that rises steeply at first, then more gradually.
