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.

. 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. This will be probably due to learning disabilities or typing errors on the datasheet.

To do this I will do a scatter diagram with a line of best fit.

I will aim to test the difference between the difficulties of the tests by making an average grade for each year by displaying them in a table with the average IQ for that year.

If there is no difference I will be able to carry on the data as a whole group rather than in years and so use a larger area on each graph. If there is a difference then I will be have to explain why and continue with the data separated between the years.

I will now do a cumulative frequency curve to show the IQ of the people surveyed. This will be useful as the distribution of IQs can be used in comparison with a pie chart of the sats results. The sats results will be shown best in a frequency polygon as they can all be shown easily and compared easily because they can be put on the same graph.

After this I will write an overall analysis and conclude my project.
