The document summarizes an investigation into the relationship between height and jumping length. 20 students aged 9-11 had their heights measured against a wall and jumping lengths measured by how far their toes reached when jumping from a standing position. On average, the students could jump 7.6cm further than their height, disproving the initial hypothesis that height would be longer than jumping length. Taller students generally jumped further, though some shorter students jumped surprisingly far and some taller students did not jump as far. The sample size was small and measuring methods could be improved, suggesting further studies with more participants and variables like age, body size and warm-up.
