Show Details

Is there a correlation between the length of someone’s hand and shoe size? While this may seem like a silly question, we've developed a full research project called the "Foot-to-Hand Ratio." This research project uniquely exposes students to units of measurement, dimensional analysis, and research. Over a period of years, a class of 24 students completed this research project. Students measured the length of one hand, one foot, and their height. Then they calculated their Foot-to-Hand, Height-to-Foot, and Height-to-Hand ratios. Surprisingly, there was a direct correlation between the hand and foot length, and height and hand, or foot, length. In addition, students used statistics to dismiss "outliers" in the data.

TAKEAWAYS:
Attendees will have access to a new, simple research project that incorporates mathematics.
