    S1 May 2012

    Not sure what to make of this paper, certainly required a little more thought than normal

    Q1 - DRV

    Easy


    Q2 - PMCC

    Easy


    Q3 - Linear regression

    Bit weird but pretty easy


    Q4 - Venn

    So stupidly easy


    Q5 - Measures of location / spread

    Very weird - you could have quite easily solved it by spotting that there were 22.5 5x5 squares so each 5x5 square represented 20 cars.

    However I think this will be a massive bloodbath with many students picking up no marks.


    Q6 - Normal distribution

    Harder than normal I would say; I used the % points table to answer b) and c)


    Q7 - Probability

    Fairly easy but pretty unusual


    I am going for

    75 - 100ums
    68 - 90ums
    61 - 80ums
    53 - 70ums
    45 - 60ums
    37 - 50ums
    29 - 40ums



    This thread will be locked at somepoint and then unlocked at midnight following the Stats 1 examination.

    I will upload the paper and my solutions to this post.

    I will do my best to answer questions about the paper but please try to read the thread first so that I am not answering the same questions lots of times.

    Here are some links to previous S1 threads, they are worth a read and you will see what the common errors were...

    The second link contains loads of past papers, model answers etc

    Good luck.

    I revised them all last night, funny feeling there was gonna be a horrible histogram question, as soon as I saw it I'm pretty sure I made a very loud noise in excitement...

    Histogram Q was good! The normal distribution part (c) was a muck-up of a Q... :/

    I knew I couldn't do them, I just hoped they wouldn't come up... obviously not a good tactic LOL.

    I was stupid enough to draw my tree diagram in pencil, do you think I'll lose marks for it? Other than that it was a decent paper.

    It seems that was the only question that got people - and it got people good! Everything else was good though, yeah.
