# Prove that Girls in Key Stage 4 at the Mayfield High School have a higher IQ Level than the Boys from the same years and school.

Extracts from this document...

Introduction

Maths Coursework Statistics

## Aim

I have chosen to prove that Girls in Key Stage 4 at the Mayfield High School have a higher IQ Level than the Boys from the same years and school.

Procedure

I intend to investigate the relationship between the Girls in Key Stage 4 and the Boys in Key Stage 4. To get my data and graphs I am going to sort and filter data from the key Stage 4 information. I am going to sort firstly by Gender to filter out all of the Year 10 Female and Male Students and will then put each into a different worksheet. I am then going to Random Sample 15 entries from the boys and 15 entries from the Girls to allow me to compare them easily. In total I will now have 30 Random Sampled entries. The graphs that I am going to draw to help me answer this hypothesis are going to be:

• Bar Graph to show the comparison between the Girls and Boys IQ Levels,
• Bar Graph to show the total IQ Comparison,
• Surface Area Graph to show the average for the Boy and Girls IQ,
• Cumulative Frequency Graph of both the Boys and Girls.

Conclusion

### Anomalies

The time I had been allocated made it very difficult to achieve 100% accuracy for my experiments. This meant that there were, inevitably, always going to be some anomalies, also because the result were gathered from a school, there will be typing mistakes and deliberate mistakes by joking pupils e.g. IQ=290. Because of these mistakes I just had to accept them as real results due to this, I have tried to avoid them. Therefore, as you can see from the graph, there are no anomalous readings taken from the charts.

## Improvements

If I were to repeat the experiment, I could make several improvements to improve the level of such factors as accuracy and the amount of random samples. For example, I could ensure that I chose at least 40 results to increase accuracy. I could also get as many opinions as possible or do different types of experiments. I could increase the number of times I carry out each of the tests with different pupils each time; this would improve accuracy even more.

## Furtherwork

If I were ever to do this experiment again, I could consider investigating another of the key factors involved with this investigation. For example, I could change the type of comparison e.g. IQ to Key Stage 2 Level.

This student written piece of work is one of many that can be found in our GCSE Height and Weight of Pupils and other Mayfield High School investigations section.

Data: Grouped data is where data is divided into groups instead of having an individual category for each data. An example would be: 50 < x ? 75 Instead of writing 50, 51, 52...etc. the 'x' represents all the numbers that fall into the group, which would be bigger than 50 but smaller of equal to 75.

handle large sets of data more easily and will be easier to use when plotting graphs. In both the height and weight column, '120 ? h < 130', this means '120 up to but not including 130', any value greater than or equal to 120 but less than 130 would go in this interval.
