Statistics Investigation Into Height and Weight Relationship
From the data I have received I have chosen to conduct an
investigation comparing height and weight because I feel there much
relevance between ones and height and weight. I have chosen to compare
height and weight because I feel I will get clear results and
therefore conduct a meaningful and knowledgeable investigation. I will
be trying to determine whether ones height has any relevance to ones
weight and then I will attempt to find out whether separating boys
from girls will show different trends and in general have much
difference from the group as a whole.
I will first investigate heights and weight for year 7 and for year 11
and as an extension I will make comparisons and comment for both
years. For my investigation I will need to start with a random sample
of 50 students (25 girls, 25 boys) from year 7. I have data from a
total of around 170 students, and the amount of boys and girls are
roughly even, hence meaning there are about 85 boys and 85 girls. To
get a completely unbiased sample of students I will be using random
selection. I have figured out that because there are around 85 boys it
will be sensible to choose every third boy in the list starting with
the third boy down the list. Theoretically this will mean that around
10 students will not even be considered at the bottom of the list
because 3 × 25 = 75 and 85 - 75 = 10. However this method of random
selection will give me a completely random and unbiased sample of
student. The exact same applies for the girls. When I have done the
random sample selection I will have a total of 50 students, 25 of
which are boys and 25 of which are girls.
I will now conduct a plan in the forms of a flow chart to show what I
plan to do and the types of things I intend on finding out.

A sample of children ranging from 4 to 13 years old are going to be asked to watch a Rainbow Brite video. The children will be randomly picked from a childcare center. To ensure that the children are going to be randomly assigned, the children will range in different age groups. The first group will consist of 4, 6, and 8 year olds. The second group will consist of 10,12, and 14 year olds. It would have to be a field experiment because you have to go out and collect the data.
The last process is called planning. Planning, formerly called Phase II, is the bridge to change. This can include making a clear plan and creating a menu of options for how to proceed.
In “ how obesity became an epidemic disease” J. Eric Oliver discusses the negative impact the perception of obesity as a disease can have on the American people. Oliver begins by explaining the advent of the description of obesity as a disease and explains the fallacies in the argument that supports this description. The author argues that the data was misleadingly presented in a biased way to suggest that obesity is a spreading epidemic rather than a consequence from personal lifestyle choices. Oliver then delves into the ever-changing role of the CDC, explaining that many aspects of the human condition have slowly been medicalized and deemed diseases in need of a cure. According to the author, it appears that the inflation of the severity of obesity is often due to the commodification of the health care system promoted by the weight-loss industry and the need for passing the CDC budget through congress. The author argues that there is no clinical evidence linking some of the most abundant diseases in America to obesity.The author then makes the

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

Planning can be used to help the organization map out a way to efficiently achieve their goals. The beginning of the planning process should include analyzing of the current situation. From this information the company can determine the goals and start to outline the steps that need to be taken to ensure that the goal will be met. Other planning activities that should be completed are determining the company’s objectives and were they want to be in the future. This will help them to choose their business objectives and strategies. In addition, the company should look at the resources that they have available and determine if they are sufficient to achieve the organizations goals.
