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. Plan
