IQ Between Students in MayfieldHigh School

Introduction

IQ Between Students in Mayfield High School Our task in this project, I chose to investigate on the IQ of students. I chose this factor because I believed that it could show an interesting results and how IQ could relate to Key Stage Results. I compared the IQ between male and female, IQ between each year group and the relationship between IQ and Key Stage 2 results. I expect to find that, as the IQ increase, the better the Key Stage 2 Results and also male students would have a higher IQ than female students. Also, students with a higher IQ would have higher KS2 grades. I would need to collect the information on IQ, Key Stage 2 Results for English, Science and Maths. I will use a sample size of 5% of each year group to keep it a fair investigation. When choosing my sample, I used the method of random stratified sampling. To do this, I numbered each student in each year group. ...read more.

Middle

The upper quartile is the value which 3/4 of the data set is below and 1/4 is above. It can be considered as the median of the upper half of the values in the set. The lower quartile is the value which 1/4 of the data set are below and 3/4 are above. It can be considered as the median of the lower half of all the values in the set. The interquartile range is the difference in value between the upper quartile and the lower quartile values. * The Relationship Between Male and Female Student's IQ - Box and Whisker Diagram, Cumulative Frequency Diagram * The IQ relationship Between different year groups - Box and Whisker Diagram, Cumulative Frequency Diagram The first investigation I did was compared the general case for IQ against Key Stage 2 Results. I did this by plotting a scatter diagram. KS2 Results will be plotted on the X axis and the IQ on the Y axis. ...read more.

Conclusion

Lastly, I compared the IQ between each year group again, using the box and whisker diagram. The graph showed that on average, year 8 has the highest IQ and year 10 has the lowest. My calculations have helped me to state that on average, the higher the IQ, the higher the key stage 2 results. Also female students tend to have a higher IQ than male students as we can see clearly from the box and whisker diagram. The IQ relationship between different year groups did not show a correlation or a pattern. However, it showed us that year 8 has the highest IQ while year 10 has the lowest. This has proven my original statements to be correct other than the IQ relationships between different year groups. I predicted that the higher grades will have higher IQs which are not correct. I am happy that my conclusions are reliable because my data did not show any anomalous results meaning I did not make any errors during the process of calculations. Francesco Chan 10J ...read more.

    each year group, I will still use the Key Stage 2 results from the Mayfield High School database. However, since I now know that the link between ability in Science and in Maths is greater for male students than for female students, I will now base my investigation on a stratified sample of 20 students from each year group.
