The document summarizes an experiment that measured the lengths of fingers and arms of 20 participants to test the hypothesis that arms are longer than total finger length. It found that on average, total finger length was 28.57cm while average arm length was 56.57cm, supporting the hypothesis that arms are longer than fingers by about 28cm.
