Data Handling IQ correlation

Extracts from this document...

Introduction

Data Handling Project

Introduction

For this piece of maths course work I am going to compare the correlation between year 10 and 11 KS2 and IQ results. I will be getting the information of the schools computer under Mayfield schools data.

Hypotheses

Having looked at them Mayfield data on the school computer I have come to this hypotheses. The higher the students IQ the higher their KS2 results will be. I will test this hypotheses by sampling the Mayfield data and constructing a box and whisker diagram.

The way I collected this data was to first go onto the Mayfield school data collection program and selected the year, gender, IQ, and KS2 level for all year 10 and 11 pupils, I then sampled the data by taking every third person to get at least 30 people in each level.

 I did not use levels 2 and 6 as there were not enough people in these groups to get a good comparison as I set a minimum of 30 people in each level.

Conclusion

Form my results I have discovered that the lowest levels in levels 3-5 go from 78 -101 this proves my hypotheses to be correct as there is a correlation between the steady increase in IQ and level.

Also from my results I have discovered that the highest levels in levels 3-5 go from 104 -124 this also proves my hypotheses to be correct as there is a correlation between the steady increase in IQ and level.

Conclusion

Throughout the work that I have shown I feel that I have proven my hypothesis to be correct. I have shown this by using a number of different techniques and skills. I have used box and whisker diagrams to compare my results and I think that I have shown my results give a good readings. I have found that the people who achieved level 3 at key stage 2 have a lower IQ than people who achieved a higher level at key stage 2.

    There are 14 girls and 14 boys who fall in the 140-149cm category. It is also common for both gender groups to be the height of 150-159cms. This shows that the girls and boys of year 7 are similar in height.

    By looking at the two tables, I can see that the modal class for each year group is 1.60 - 1.75 metres. The difference is huge in year 10 but in year 11 the difference is very small and by looking at the data it could be said that more people in year 10 are taller which is very surprising.
