For my third hypothesis I am doing the older you get the more weight you will put on this is because this database is all students who are teenagers- these are all growing so logically the more they grow the heavier they will be.

Claire Wightman Maths Coursework Mr Parry My 3rd Hypothesis For my third hypothesis I am doing the older you get the more weight you will put on this is because this database is all students who are teenagers- these are all growing so logically the more they grow the heavier they will be. To prove this I will collect 20 random samples firstly from year 7 and then year 11, firstly I will check it for correlation. I will plot these results in a cumulative frequency diagram and then compare the average weights of year 11's to sevens to see if they are higher; if they are then my hypothesis will be correct. Here is my data No. Year 11 weight (kg) Year 7 weight (kg) 1. 60 45 2. 63 40 3. 51 40 4. 51 45 5. 63 45 6. 52 57 7. 39 38 8. 63 45 9. 54 47 10. 60 50 11. 84 47 12. 55 54 13. 86 57 14. 48 31 15. 48 40 16. 50 49 17. 76 45 18. 62 39 19. 55 47 20. 48 42 I will now use this data to produce a scatter diagram. So is my hypothesis correct? * There was a positive correlation in my scatter diagram, which would indicate this is the case...
