• "Sniff and Die: A Test of Inhalants" by Kirsten Hansen from Beaumont School in Cleveland Heights. This project com-pared means taking into account variation.
• "Results of a High School Questionnaire: Non-Traditional Occupations Impact on Relations" by Nida Degesys from Mayfield High School. This project summarized associations using two-way frequency tables and chi-square tests.
• "How Far Will Your Golf Ball Go?" by Robert DiMarco from St. Rita. This project compared the distance travelled of four types of golf balls using a home-built "driving" mechanism to apply uniform hits to the balls. The best ball was the Top Flight Strata as determined from _ t tests comparing the mean distances travelled of the three types of balls to the distance travelled by the a priori "best" ball.
• "Butane and Beyond" by McKensie Koss and Caroline O'Neill from St. Bernadette in Westlake. This joint project evalu-ated whether temperature affected the molecular mass of butane. Differences were shown by using stem and leaf, and box plots.

• "The Effects of Auditory Distractions and Age on Response Time" by Trevor McGrath from Mayfield High School. This project showed scatter plots and regression lines to examine the relationship between auditory distractions (such as loudness) and response time.
• "Rocky River Sedimentation" by Tom Blank from Lakewood High School.
  
• "The Impact of Different Number of Spiders on Prey Capture and Web Strength" by Elisa Jones of Hathaway Brown. This project used a clever design and summarized the data by means and standard errors.
  
• "The Bell Curve" by Hannah Hilow of Our Lady of Good Counsel. This project showed that dropping balls through a series of pins resulted in an approximate "normal" distribution.
  
• "Comparative Study of Body Mass Index of Female and Male Teens" by Hac Bui of Cleveland
