    statictic coursework part 2

    Right ive progressed from my last post, i have asked my maths teacher what should i put in my "writeup" and he told me that i have to write down everything i done and a few other thing, they were "how can i improve my hypothesis" and " by taking 30 peices of data from each year group and comparing their correlation". * these are both writen on here as my teacher wrote on a piece of paper.

    I have 2 questions, how could i improve my hypothesis?, i asked people in my class and they said " i duno its your data it diffrent to mine" now i dont know if this is true or they cant be botherd to tell me so can anyone else tell me how i can improve my hypothesis.

    and the other 1. i dont know if this is badly writen by my maths teacher but what does " by taking 30 peice's of data from each year group and coparing their correlation" mean?

    This is for UK, GSCE statistic's coursework

    can anyone help me as my teacher is now unwilling to aids us anymore after he has done for 2 weeks(not good)

    cheers

    What is your data, and for that matter what is the hypothesis?

    The hypothesis is "the taller you are the heavier you are" and the smaller you are the lighter you are" and what do you mean "what is your data"??
