Introduction

For this coursework I will be going to find out about a factious high school called Mayfield High School. My lines of enquiry are the Relationship between IQ and Key Stage 2 results. My Hypothesis are boys have a higher IQ than Girls. And that girls are taller than boys. For my sample size I have chosen 84. This is due to the fact that if I have chosen a lower number the results would may become bias. And if I had chosen a very high number it would take to long to do. In order to begin with, I would do a stratified sample. It is stratified so you can represent population and it also awards bias.coab abr seababw orab abk inab foab ab.

Despite most of the girls and boys having the majority of their IQ's in the 100-110's. 12 out of 30 girls are in this category. Whereas only 11 out of 30 boys. This is easily seen. This essay from www.studentcentral.co.uk

My evidence shows the average boy is brighter by 5 than of the average girl. Also another thing my evidence shows is that the boys IQ is more spread out with 42 as its range rather than the girls which has 29 as its range.cogc gcr segcgcw orgc gck ingc fogc gc.

As with the IQ I can see the obvious differences between the girls and the boys heights. But the data is not shown in a way in which I can compare it, so that is why I am going to put the two sets of data into one frequency polygon Carstens oppressed channyman69's realism .

Now with these more even detailed results, I can now see the exact frequency of each of the people heights, into groups. As with graphs you cannot actually tell. It could be that point in the group 140<H<150 could be 140cm. So I feel it is good to see what exact points you are dealing with. I can now work out the mean, median and range of the data. The results are as follows:- Carstens denied channyman69's structuration .

From this results my modal for the girls is actually higher than the modal of the boys. This is very visible on my frequency polygon. As the girls line reaches higher that the boys line. This not actually does follow my hypothesis because just because the modal is higher does not mean the group which has the greatest height. But the median height is actually the same for both girls and boys. But when it is the range of results similarly to the IQ the boys' range is higher than the girls. It has the difference of 8 between them. Of what I have done , my conclusion are only based on a random sample of thirty boys and 30 girls. So they are not 100% accurate. And I will sometime extend my sample later in order to make it more accurate. I feel now that it is time for me to work out the quantities and medians of the both sets of data. As this will be grouped data so I can make stem and leaf diagrams. channyman69, please do not redistribute this paper. We work very hard to create this website, and we trust our visitors to respect it for the good of other students. Please, do not circulate this paper elsewhere on the internet. Anybody found doing so will be permanently banned.

So to do this I am going to produce cumulative frequency graphs as this is very good when comparing grouped continuous data. And I can make a further conclusion when comparing the heights and the IQ results separately. I am also going to make box and whisker diagrams on the same curve because this will allow me to find the median, upper and lower quartiles and inter-quartile ranges much easier. I am firstly going to look at the IQ and make the best match possible I am going to put boys and girls mixed on one graph. channyman69, please do not redistribute this work.

The upper quartile is the value three quarters of the data. And one quarter is above. The lower quartile is 1 one quarter of the data set. And three quarters are above. The inter quartile range is the difference in value between the upper quartile and the lower quartile values.cogf gfr segfgfw orgf gfk ingf fogf gf;

When looking at my cumulative frequency graphs for IQ and Heights I can say they are kind of the same. And there is no relationship between the IQ and Height as of yet. I am now going to extend my investigation so that IQ and Height can be related. The best way to do this is to make a scatter diagram. I am going to do girls and boys separately because it will make a stronger correlation. The good thing about scatter diagrams is they allow me to compare the correlations of two graphs. And get the line of best fit for each girls and boys. Mfjk5c6sP Visit coursework dc in dc fo dc for dc more cours dc Do dc not dc redistribute Mfjk5c6sP

This graph also shows a strong correlation and this correlation is about the spread for both the boys and the girls. Most of the points on the graph are mostly next to and near each other. This is round about the same on the boys graph as well. Since both my lines of best fit are straight the line of the equation would obviously be y=mx+c. Where y would be the IQ and X be the height in centimetres. This means I could predict results.
