Body Measurement Experiment Shane Cozort September 27, 2011 Biology 2010-51 Professor Martin Subjects: Gena Lyn, Kayli, Laura Beth, Karen, Morgan, Sara, Taylor, Cassi, Robin, Aaronda, Lauren, Mary Intro/Observations/hypothesis With the correlations among height and limb length, a study was conducted using the Scientific Method to determine if the arm has a direct relationship with the height of the person. The subjects for this study were 1 male and 12 female from Tuesday 1:20pm A&P lab class. These subjects were randomly selected and grouped by Professor Martin. These calculations can be of use in determining skeletal deformities, abnormalities of the spine, or if limb length is predictor of height. The aim of this study is to approve or reject the hypothesis being limb length (arm) is equal to 40% of a person’s height. Procedure/Experiment/Materials 1. Materials = Yard Stick, Calculator 2. 13 random subjects selected in Bio Lab 2010-51 3. Standing erect, a measurement was taken from the axillary to the longest finger tip of each subject 4. Standing erect, a measurement was taken of each subjects height minus shoes 5. #3 and #4 data was collected from each subject and logged 6. Height was multiplied by .4 to determine expected upper limb length and logged 7. Upper limb length was divided by height to give actual % of height and logged TABLE 1.1 Subject: | Measured Upper Limb Length (cm) | Height | Height x 0.4= Expected Upper | Actual % of Height = Upper Limb Length (cm) Height (cm) | Shane | 71.5 | 178.6 | 71.4 | 40% | Gena Lyn | 62.9 | 155.6 | 62.2 | 40.40% | Kayli | 76.4 | 163.9 | 65.5 | 46.60% | L.B. | 68.1 | 167.3 | 66.9 | 40.70% | Karen | 60.5 | 159.8 | 63.9 | 37.90% | Morgan | 66.1 | 158.4 | 63.1 | 41.70% | Sara | 64.3 | 157.8 | 63.1 | 40.70% | Taylor | 67 | 170.2 | 68.1 | 39.40% |
