    I am studying the effects of concentration levels in children after playing computer games.
    I can find no similar research online for this? can anyone help. i really have searched for ages and cant change my study at this point.

    My alternative hypothesis is that ' there is an association between levels of concentration and the playing of computer games”


    The null hypothesis for the study is 'children to play computer games have the same levels of concentration levels than those who don't play computer games'

    I think i have to do t-test for unrelated scores? is this correct?

    Please help

    thanks in advance
