Hypothesis: Wearing red on the day of an exam “energizes” the brain and improves performance.

Independent variable:


 * Shirt color
 * Educational background
 * Type of test (SAT)
 * Ethnicity
 * School
 * Grade
 * GPA
 * Testing center
 * Room temperature
 * Time of day
 * Weather
 * Length of test (4 hours)
 * Number of students participating (100)

Dependent variable: results of the exam.


 * Students will not have taken the SAT beforehand and will be freshmen from KIS. They will be randomly selected with roughly equal numbers of girls and boys.
 * This will be a double blind study so that those providing the shirts will be unaware that they are participating in a study. This is to avoid self-fulfilling prophecy. Half of the students will be given a red shirt; the other half will be given shirt of any other color.
 * The results will be compared to find if the difference in performance, if one exists, is due to the independent variable and not to error or chance occurrence.
