The document summarizes an experiment to investigate the relationship between total finger length and arm length in 15 Grade 4 students. Measurements of each finger and the arm were recorded and it was found that 14 out of 15 students had arm lengths greater than their total finger lengths, supporting the hypothesis. On average, arm lengths were 13.18cm greater. The conclusion is that for 9-10 year olds, arm length is typically greater than total finger length. Limitations around sample size and measurement accuracy are discussed.
