Aim: To find the differences in human size from measurement
Apparatus: Seven to five friends, measuring tape
1. Choose five/seven friends
2. Take height of each person
3. Record data in appropriate manner
4. Process data collected
5. Make evaluation
Observation: The males in most case were taller than the females and had a general height of 5 feet 8 inches, while the females remained in the area of 5 feet and 1 inch to 5 feet and 2 inches. Theory: Every human is not the same there are slight to major variations in size with every human being. Human variability, or human variation, according to the Wikipedia online encyclopedia is the range of possible values for any measurable characteristic, physical or mental, of human beings. Differences can be trivial or important, transient or permanent, voluntary or involuntary, congenital or acquired, genetic or environmental. Analysis of data: The general height for males was about 5 feet 8 inches with only two exceptions being half and third of an inch taller. The females however were much shorter the tallest being 5 feet 2 inches. Height with the males may have shifted a little based on head shape and body structure, whereas the females having much more hair could’ve added the extra inches of difference. Source of error: Shoes and hair could cause inaccurate measurements, poor posture and cranium structure. Tape measure may not have had accurate measurements. Limitation: Experiment could have been carried out again with different measuring apparatus to clarify results. Evaluation: Males in the group are much taller than females but they height is average all remaining in relatively the same range whereas, the females differ in inches each girl’s height increased by an inch.
