- Method:
The data of 20 males and females within age range of 19 to 23 will be collect. The data will be presents in a table, which include note and BMI. Graphs will be sketch base on the data table. BMI will be used to determine the balance of body.
BMI=Weight (Kilograms)
Height2 (Metres)
- Results:
There is no overweight or obese people in the data table, most of them are underweight and balance as their BMI results are below 18.0 and between 18.5 and 24.9 respectively. Some of the people are extremely underweight. General trend in the data is males are heavier than females even at same heights. Males also have bigger shoe sizes than females. In addition, genders seem to have affected on heights, weights, and shoe size. Moreover, there are relationships between heights and weight, height and arm span.
- Discussion:
There are some relationships between heights and weight, arm span and height, gender and weight, shoe size and gender.
There is a relationship between weight and height. For example, person # 3 is 1.78 m tall and weighs 78 kg; person # 8 is 1.82 heights and weighs 82 kg; thus, weight can be determined by height. Arm span can be used to measure the height of a person. Example, person # 9 is 1.70 m tall and arm span of 1.71 m, his arm span is similar to height. Hence, we can measure his height by simply measure his arm span.
Males are heavier than females. For example, male # 2 and female # 20. Both of them are 1.71 m tall, but the male weighs 65 kg and the female only weighs 52 kg. Hence, males are heavier than females even with same height. In addition, genders do affect on shoe size. For instance, male # 5 and female # 15. They are both 1.68 m height, however, the male has shoe size of 9.5 when female shoe size is only 6.
The data of body mass can be useful to medical people to determine the health of people. Height and weight can be analyse if a person is balance, underweight or overweight.
- Conclusion:
After investigated the body mass data of 20 people and analysed their weights, heights, arm spans and shoe sizes, we can conclude that gender has influenced on weights and shoe sizes. There are relationships between heights, weights and arm spans. BMI data can be used to determine if someone is balance.
