Investigate the relationship between the IQ of selected students and their Ks2 Sats Results.

Extracts from this document...

Introduction

Course Work Plan. Question For my course work I plan to investigate the relationship between the IQ of selected students and their Ks2 Sats Results. Prediction I predict that the higher the IQ the greater the KS2 results will be. I came to this prediction as the IQ is the potential of a person, so if a person has more potential then they should be able to achieve a higher grade with the same amount of work. Eg IQ Ks2 Results EN MA SC 92 3 4 4 103 4 5 5 Methodology For my project I am going to use a pre collected datasheet from this I must make the following assumptions about its reliability. 1. This data was collected accurately. 2. This data was collected fairly. 3. The datasheet I am given is complete. I will make sure my sample is a fair sample by selecting my fields using the random function on my calculator. This will mean I get a purely random sample. I will collect 10 random samples from each year of either male or female. Using the random sample function on my calculator I will take these samples form the complete datasheet. It is important to be able to distinguish between the years as different years had different tests so this may change the results. In my first sample I am going to compare each year to see if they have a similar pattern and explain any anomalies found. I will then have to explain why these may have occurred. ...read more.

This is a graph to show the relationship between the year 8 English sats results and IQ it shows a very strong positive correlation and does support my prediction. This is a graph to show the relationship between year 9 KS2 sats results and IQ. ...read more.

Conclusion

These two cumulative frequency curves show that both the IQ and the sats result are related. I know this a s the graphs follow a similar curve as each other. This means that my prediction is also proven by my cumulative frequency curves. Conclusion I have found by conducting my project that the greater the IQ of a student the higher the level achieved in the sats tests. This proves not only that my prediction was correct but the sats exams are successful. I know this as the exams are used to show that a person with an average IQ (90-110) should achieve an average grade of level4 this is shown in most cases to be true. This shows that the British lower school education system is also achieving their targets and doing there job properly. This is important as if it they were not achieving their goals in most cases then the methods must be re addressed. This will not be true for some of the cases as they may have learning or behavioural difficulties which will affect their grades. All of my graphs have shown that as the IQ increases so does the level achieved in there KS2 exams so there potential is being met. To prove this I had to find evidence for this statement which is shown in the tables I have done in the previous section and especially well on my cumulative frequency curve. As both the the IQ and the sats level gave very similar curves which would imply a strong correlation between the two. Summary of conclusions As the IQ increases, so does the sats level attained in each subject. - 1 - ...read more.

    Therefore, I think that pupils with Maths as their favourite subject will generally have a higher IQ. I will need to look at a sample of about 50 pupils. I will use a stratified sample to get a fair representation of each favoured subject.

    lower boundary is lower than the females and therefore the majority of their results could be lower than the females.

  1. High IQs

    As I am doing a line of enquiry that is targeting children of a certain abilities group, my sampling will not be random. It will have to be stratified. Once I filtered out the data I need (children with an IQ over 95), I chose a random sample of 50 using the Random Command button on my scientific calculator.

  2. Is there a link between IQ and Key Stage 2 results?

    There are 1182 pupils in the spreadsheet and I shall base my investigation on a sample of these students in order to save time. A sample is smaller group taken from the population which should represent the population. Sampling saves time but can make the results inaccurate as the sample may not fully represent the population.
