    Criteria for students
    Hi Paddy - My advice - students could show the stages of a chi2 independence test using a spreadsheet. As such, all the stages of the calculation can be seen.... If you look at the student writing guide on this page there is a worked example...

    Hi Jim, just to follow up on your comment in the General Advice for Criterion C... Do you expect the student to actually show manual calculation of the Chi Sqd Calc value to justify a sophisticated process? Or once they've shown how to get...

    Hi Jim, Paper 1 question 14 has a typing mistake. You repeated age 12 twice in the table.

    Thanks Jim. I actually like it with the raw data left out, as a good talking point for students when they do a practice moderation of this piece. Would suggest amending your B score to 1/3 and showing students how that can make a 1 or 2 mark...
