# The relationship between IQ and Key Stage 2 results

The relationship between IQ and Key Stage 2 results

The aim:

To compare the KS2 results with the IQ’s to identify whether IQ will determine their results.

Hypothesis:

There are many different lines of enquiry, such as:

• The variations in hair colour
• The variations in eye colour
• The relationship between hair and eye colour
• Shoe sizes
• The distance travelled to school
• The relationship between shoe size and height
• The relationship between height and weight
• The relationship between Key Stage 2 and/or 3 results
• The relationship between IQ and Key Stage results
• The height to weight ratio in terms of body mass index

I have chosen to investigate the relationship between IQ and Key Stage results. I believe that the higher the IQ, the higher the KS2 results. This is because IQ measures how intelligent a person is and key stage results reflect knowledge and retaining of information. I will try and prove this by comparing the average KS2 results, years 7 to 9, to their IQ’s.

The Data:

I have collected some secondary data, and from it I must take a random sample of the information I need. I will do this by using my calculator. I have given each page a number, and then the names on that page also have numbers. I will then press ‘shift’ and then ‘RAN#’ on my calculator, and it will display a number between 0 and 1. I will then multiply this number by 34 each time, and using the unit, I will find the page, and using the decimal, I will find the name. E.g.

0.283 x 34 = 9.622

9 is the page number and 6 is the number of names I must scroll down. I will do this until I have found a sample of 20 girls and 20 boys.

I have now done that and the information I collected is in the table below:

Data for each pupil was provided, such as name, age, year group, IQ, height, hair colour, eye colour, number of siblings, KS2 results, distance travelled between home and school, and gender. I have used gender, IQ, and KS2 results. From this I have drawn three scatter graphs.

Graph A: the results of both boys and girls

I predict that graph A will show positive, and relatively strong correlation. This shows that the higher the IQ, the higher the KS2 result and the lower the IQ, the lower the KS2 result.

Graph A shows relatively strong, ...
