I am going to use secondary data for my investigation. I have acquired my data from the website www.mathsmatrix.co.uk. The data is based on a real school but the name of the students and the school has been changed. The data is presented as a single list of 1183 pupils, from year 7 to year 11. I have chosen to investigate two lines of inquiry. The relation ship between height and weight and the relationship between IQ and KS2 math's results. I will choose a sample of thirty boys and thirty girls randomly. This can be done using a number of methods. I have used the random number button on my calculator.
