Data Presentation Maths Coursework

Introduction

For my math’s GCSE course I am required to complete a number of projects. These will include number exploration and data presentation. This piece is my Data presentation coursework. For this piece I am required to collect a set of data from a data source following lines of enquiries and then presenting and evaluating that data.

The Data Source

I will be collecting my data from a database containing data from a fictional school. The school itself is fictional but the data on the students is real and has been collected from real people. The data on Mayfield high is as follows;

Year

The total number of students at the school is 1183.

Lines of Enquiry

I intend to collect data based on two lines of enquiry these are as follows

Height – Weight

Sampling

Sampling is the method which I will be using to collect my data. I will be using stratified sampling as this is the only fair way of making sure that each year and sex group get the proper ratio of samples. This method prevents the minorities getting a major effect on the data and ensures that all groups are taken into account.

Conclusion


Conclusions

  1. I believe that my first prediction of “taller the person, the heavier they will be” is correct. As can be seen in graph 1, there is an incredibly strong relationship between the height and weight of a person. The trendline generated by Microsoft Excel backs this fact and shows that the taller the person, the heavier they are. There were only three anomalies in this data, which means that the variation in the data is fairly minimal.

2.  I also believe that my second hypothesis of “I believe that girls will be shorter than boys across all year groups.”  Is true due, mainly to my graph. The bars show that girls are shorter than boys (except for in year seven) and that girls apparently shrink in year eleven. This anomaly in year eleven is due to the sample size for year eleven only being 5!!!

Extended Research

This Chart simply shows the proportion of the heights in the school. From this I can see that over half of the school, including all years is between 1.5 and 1.75 metres tall. From the above graphs I can see that most of the people in this group are between years 8 and 10

The below radial diagram again shows the difference between girls and boys height. As above it shows that boys are generally taller than girls.

    I will then plot the interquartile range. I will do this by dividing the cumulative frequency into four quarters, then I will go across to the curve, and then go down and read off the value it gives. From there I should be able to see on average who is taller out of year 7 pupils and year 9.
