Summary

At the 2025 DataFest, students analyzed nearly 200,000 office lease records to predict whether tech companies would relocate or renew their leases. They tested three statistical models and found office size, year, and space type were key factors in these decisions.

Non-Routine Problem Solving

Level I (9th & 10th Grades)

Interesting problems requiring ingenuity rather than high mathematical
skills to solve. Arithmetic, basic algebra, knowledge of intuitive
geometry, and number sense are used.

Level II (11th & 12th Grades)

Intriguing problems requiring ingenuity, logic, number theory, basic
algebra, geometrical relations to solve rather than depending on highly
developed technical skill in a branch of mathematics.

Sigma Award

This award is designed to recognize two schools as the all-around winner in their division. A trophy will
be given to both a large school and a small school. To determine the winner, points will be awarded to
those individuals and teams earning first, second, and third places for each event. The points will be
awarded as follows:

• Each team event will earn 16 points for 1st place, 10 points for 2nd place, and 6 points for 3rd place.
• The individual events will earn 8 points for 1st place, 5 points for 2nd place, and 3 points for 3rd place.
