Because there is an even number of girls and boys I won’t have to use a stratified sample. This is normally used to make sure you have the right amount of girls and boys depending on the difference between them. Eg.140 girls =14 ran numbers 120 boys = 12 ran numbers even though when added up it is not equal.

I will do 2 lines of enquiry:-

    By drawing a stem and leaf diagram, I found calculating the averages (for example, means, medians and modes) easy. I also easily worked out my upper and lower quartiles. I have presented my results in the following tables. Results Table for Heights This table shows the heights of the girls and boys from years 7, 9 and 11.

    This shows that the Male IQ are more evenly and closely distributed than the Female IQ and their KS2 results have a similar variation. In Conclusion, this shows us that the relationship between the IQ's and KS2 Results are more closely related for Males than for Females.

  1. Data handling

    from the cumulative frequency graph along with the maximum and minimum values. * Cumulative frequency graph. A cumulative frequency graph comes out as a curve that looks like a 'stretched S' is called an ogive. The more stretched out the 'S' shape is, the more spread out the values are.

  2. Mayfield data handling

    This makes my findings very reliable. The least accurate finding would have to be of students that achieved a KS2 level 4. This is because nearly half of Mayfield High School achieved KS2 level 4 - 552 students to be in fact. Because there are a huge number of students that achieved a level 4, it could show different trends achievements within that variable.
