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

Tallest Year 7 - 1.97                    Smallest year 7- 1.25

Tallest Year 11- 1.88                   smallest year 11- 1.52

                          Heaviest Year 11- 75                    Heaviest Year 7-69

 (Tally below will show you the height from the lowest to the highest ((year 7-11))

Year 7

Now as you can see in this height frequency chart, the most height that’s they year 7 boys are is between the mark 1.50 and 1.60 which is quite a reasonable height for the tear 7, and he least height the year 7 are in is between the height 1.80-1.90. There is no year 7 in that mark of height.

As you can see from this weight frequency chart   the most weighed boys in the year are between the marks 40-50 which is about 6-7 stones. For a year 7 that is a reasonable size weight for the year. But as you can see in the chary there are year 7 boys hitting the mark, 60-70 that is about 10-11 stones on the scale. 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 ¾ stones) and the lightest year 7 is 19 (which in stones is 3 stones)

Year 11

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.

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 ½ -14 stones, that is quite heavy for the ages of 15-16 (yrs).  Overall the most weighed year 11 is 75 (which in stones is 12 ½ stones and the lightest year 11 is 42 (which in stones is 7 ¼ stones)

Problem/ plan of my hypothesis towards this coursework.

 

In this mathematics coursework I am going to investigate the difference between the height and weight of the year 7’sto the height and weight of the year 11’s. My hypothesis for this main topic is that I am going prove that all year 11’s are taller and weigh more then year 7’s and that the year 7’s   are smaller and les heavier then the year 11’s in all aspects, “we would probably think that it is obvious that the year 11’s are taller and heavier then the year 7, and the year 7 are smaller and are less heavier”, but I am going to prove hw they are and what are the differences between the height and weight ad the year 7’s height and weight. Also from this I am going to make statements, which will be TRUE and UNTRUE towards the height and weight of the years 7 and year 11, which will be justified in this mathematics coursework!

Sample of children

YEAR 7= I have chosen 49 year 7

YEAR 11= I have chosen 31 year 11

Conclusion

As on pages, 1 and 2   you can see the difference between the height and weight of the year 7 and the year 11’s “that” the year 11’s are taller and weigh heavier then the year 7’s    From the tally frequency chart of the year 7 and 11 it supports my point dramatically and is justifies my hypothesis with full understanding.   If you look above at my chart of the 2 grade years, you will see on the year 7 chart (height) 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.
