The Relationship in Height and Weight of Students
INTRODUCTION
In this investigation, I intend to find out whether there is a
relationship in height and weight in students, and how this
relationship changes between girls and boys, with age. I have chosen
to investigate the relationship between the height and the weight as I
think that the height and the weight are the only two categories that
will give a clear correlation. If I was to investigate the
relationship of two other categories, like the eye colour and the IQ,
I believe that however interesting and amusing the results would be,
they would not provide too clear a relationship, or any conclusive
information.
The data provided gives information about 1183 girls and boys at
Mayfield High School, who have been categorized into their year
groups. These year groups begin with the students entering their
teens, and end in their mid-teenage years.
In order to be able to compare girls and boys in each year, I will
represent the distribution of heights and weights for both sexes in
each year in various forms. I plan to use stem and leaf plots, scatter
graphs and box plots, and a wide range of calculated data, like the
mean of the heights and weights, their interquartile range and their
Body Mass Index.
The data that will be represented will not be all the data provided,
as if I were to do this, then I would be plotting 2366 datum points
which would be ideal, however time does not allow for this number of
points. So, instead I will take a stratified sample of the total data
and use this sample in the investigation.
From these representations of the data, conclusions will be drawn as
to how the relationship between height and weight changes with age and
sex, but before this is done, any anomalous data points will be
considered, so that they do not affect the overall conclusions.
Hypothesis
The following hypotheses have been made, to predict the outcome of

My subject is a nine year old female. She attends the fourth grade which is average for her age. Her height is four feet three inches, and her weight is eighty-five pounds. According to www.disabled-world.com average height for a nine year old female is “47 inches” or three feet nine inches, and the average weight is “63.8 Ibs.” This would mean that she is above average in both weight and height. Being above average in weight does not necessarily mean that a person is obese, it just means they are above average in weight for the population, and in my subjects situation off by just a little. In terms of BMI(Body Mass Index) my subject scored 23, which is in the normal range. This means that my subject is considered healthy in terms of weight, and because of this has a lower chance of getting diseases like diabetes, high blood pressure,heart disease, and high cholesterol levels.
Our future begins with the children of today growing up to be the adults of tomorrow. “Childhood obesity is the condition of being overweight or severely overweight which causes risks to health between the age of 2 and 19” (“Childhood Obesity”). Childhood obesity is taking a huge toll on not only the physical standpoint of the child, but also their mental stability. Childhood obesity is no longer a concern with Americans; it’s now a problem that has spiraled out of control in the world. Obesity will never be resolved one hundred percent, but it’s the little impacts that concerned citizens bring to people’s attention that make the difference. One step in the right directions is better than not taking a step at all. Along with the many health issues associated with childhood obesity, there are three major effects that seem to stand out more around the world; the food we subject our bodies to, setting a pattern for the next generation(s), and it contributes to a child not reaching his or her full potential in life.
Obesity is not a disease. It is a condition where our body stores excessive fat and affects our health or well-being. Childhood obesity is a major cause for disease and health risks which may be lifelong. Childhood obesity is becoming a threat to society because of its prevalence. Obesity reduces life expectancy. Childhood obesity is an epidemic in the United States. The number of obese children has increased and doubled within two decades. (Helping your overweight child." Pamphlet by: National Institute of Diabetes & Digestive & Kidney Diseases, National Institute of Diabetes & Digestive & Kidney Diseases, 1997, p. 2+.) The childhood obesity epidemic requires more prevention focused on the first five years of a child’s
Obesity has risen over the years. The United States now has one of the highest obesity rates. Bad eating habits are usually the cause of this pandemic. For the past few decades, college dorm foods have led to these habits. The more unhealthy food choices are, the harder it is for people to resist these foods. Colleges serve a variety of unhealthy food in their dining halls that contributes to students’ lower GPA. By eating healthier, students can maintain a healthy weight, focus better in school, and increase their school performance to a higher grade point average (GPA).
Today, it is no secret that America is overweight. Although we still remain the land of the free, we are looked at by the rest of the world as “the fat country”. This is a label that we are not proud of and each day more and more people are becoming aware of the new epidemic called Obesity. In the article “Childhood Obesity in New York City Elementary School Students”, the author Lorna E. Thorpe discusses the numbers and statistics of how many kids are really overweight. “ Findings from the most recent National Health and Nutrition Examination Survey indicate that in 1999-2000, the prevalence of obesity among children aged six through eleven years was 15 percent” (Thorpe et al. 2004). Previous surveys show that in 1960 the obesity rate was five percent, and in eleven percent in 1988-1994. From looking at the information in the surveys you can easily see that the obesity rates are climbing rapidly. With obesity, come many dangerous side effects, both short term and long term. Short term side effects of obesity are “adverse effects on growth, blood pressure, blood lipids, and glucose metabolism” (Thorpe et al. 2004). Long term effects consist of “greater risk of hypertension, diabetes, cardiovascular disease, gall bladder disease, and osteoarthritis” (Thorpe et al. 2004). Along with physical effects of obesity, a child will also experience many physiological effects also. “Negative self-image, decreased self-esteem, eating disorders, and lower health-related quality of life” (Thorpe et al. 2004) are all examples of the physiological side effects. These can have a severe impact on a child’s outlook on life as he or she gets older. Although these side effects are prevalent to childhood obesity, no child should have to go through the...

In the past decade, research showed that in the process of education in some countries, girls do better than boys, this problem was called ‘a boy’s problem’. The Dutch Ministry of Education published the study which examines the boys’ and girls’ position in primary school based on previous studies (Driessen, Langen, 2013). As a matter of fact, this problem is not a new question, and there are many discussions about gender differences. An important part of the problem is that boys’ scores are far below those of girls. In all education, based on some researchers' opinions, involving spatial and mathematical reasoning, skills, boys always doing better than girls, but in the aspects of language application and writing, girls often do better than boys (Bonomo, 2010).
Research question: Is there a relationship between the winning time and the body mass index

Do we ever think about how many children suffer from obesity? Many people haven’t realized that childhood obesity is slowly becoming a serious problem here in the United States. Our government should take childhood obesity very seriously to solve this problem. The government along with other citizens should care about childhood obesity is because everyone here is a human being. Every child may not be affected by this problem, but there will always be a child who is suffering from obesity. The government must also care because many of those children can possibly be the future of our country. If they deprive those children from getting any type of aid then the country is also losing their next engineers, doctors, or police officers. There are several causes of obesity and there are also many solutions that need to be found to solve childhood obesity. Overall childhood obesity needs to be taken seriously as there are many parents who are in desperate need of help for their children.
When one hears the word obesity thoughts that may come to mind are overweight, big, or even unhealthy. "Obesity is defined as having a body mass index (BMI) of greater than 30" (Obesity).
