# Comparing the height and weight between the year 7's and the year 11's.

Extracts from this document...

Introduction

Mathematics Coursework 2 November 2003 1) Specifying Problem and Plan The problem and plan of this coursework is that I am going to investigate in comparing the height and weight between the year 7's and the year 11's! As a choice I have chosen 49-year 7's and 31-year 11's. I have not put the numbering of the year 7's in order I have bundled the entire name's of the pupil's up and put them in the list, this has also been done to the year 11's as well. For example, 3,58,100,34,56. I have used them in mixed numbers so that they are not copied as they were they are copied in a very different way! (As shown in the table of year 7 and 11's) 2) (Collected data on separate sheet stapled as you can see clearly) 3) Discussing results. Height (CM) Year 7 Tally Frequency 1.20-1.30 1 1.30-1.40 1 1.40-1.50 9 1.50-1.60 22 1.60-1.70 13 1.70-1.80 2 1.80-1.90 0 1.90-2.00 1 Well as I have discovered between the year 7 and year 11 that the year 7 weight towards the year 11 weight is not that much of a difference because now obviously they are in ...read more.

Middle

That is the unexpected weight of a year 7 at the age of 11 (years). Overall the heaviest year 7 is 69 (which in stones is 1 3/4 stones) and the lightest year 7 is 19 (which in stones is 3 stones) Year 11 Height (CM) Year 11 Tally Frequency 1.50-1.60 4 1.60-1.70 12 1.70-1.80 7 1.80-1.90 5 In this, the height frequency chart for the year 11 is quite tall, because the most year 11 are hitting the mark 1.60-1.70 which is quite tall including the CM marks 1.70 straight up to the 1.90. Weight (Mass) Tally Frequency 40-50 5 50-60 14 60-70 9 70-80 2 The year 11 weight is quite light most of them are in the mark of 50-60 which actually is quite a reasonable weight because between the mass of 50-60 that is about 10-11 stones. Also as the height of the year 11 are quite tall the weight 60-70 is a reasonable weight for them to, because that is about 12-13 stones. Bu t at the weight of 70-80, which is 13 1/2 -14 stones, that is quite heavy for the ages of 15-16 (yrs). ...read more.

Conclusion

is between the Meter's of 1.40-1.50 which in feet is 5 feet, is the height category most year 7 are in, but in the year 11 chart (height) is between the Meter's of 1.60-1.70 which in feet is about, 5ft 8 inches to 5ft 11 inches. Now as comparison to the year 7 they start all from the height of 1.20 and the year 11's start from the height of 1.50, despite that one year 7 is taller then the other year 11's (1.97, height of the tallest yr 7 out of them all, including the year 11's as well. That is between the mark of 1.90-2.00), if you look back at that chart, you will see that the rest of the Meter's between the year 7 and the year 11 is that the year 11's are the tallest and weight heavier! I hope that you are justified with this statement regarding to the height of the year 11's towards the year 7's. We would obviously know that as the year 11's would grow they would become much taller and heavier then the year 7, but it had to be explained in detail that in this coursework that how in these charts the year 11 are taller and heavier then the year 7's. ...read more.

Girls Gradient = 1.6 Intercept = 113 y = mx + c y = 1.6x + 113 x = y - 113 1.6 So if a girl is 161cm tall the equation of the line would suggest If y = 161cm then X = 161 - 113 = 48 = 30 (30 + 25 = 55)
