    Testing question (If the reliability and variance )

    If the reliability and variance of a test are 0/36 and 4, we can be 95% sure that 15 as a score lies between :

    a) 14.28-15.72
    b) 4-16.44
    c) 5.56-16.44
    d) 11.8-18.2

    How can we answer these kinds of questions?

    5jj, do you have any idea about the answer? The whole meaning is a bit vague to me!

    I have no idea what the answer is. I failed my first year Stats in 1965, and haven't looked at such things since.

    Re: Testing question (If the reliability and variance )

    I think you need to find a Maths forum. This really isn't an English question. I got a C at O Level Maths and my two most detested sub-subjects were statistics and probability.
    Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
