I always check the InThinking site before any Maths Studies lesson to check for an exciting introduction to a topic or for extra resources. It has been invaluable for my teaching of this course, especially the links to videos on youtube and the worksheets....

    Hi Edward, Good question, but I think the answer is no. We are quite new to MB here, but I have used it this year to upload ToK stuff. Looking around, I think you are right about the regular assignment.

    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...

    Criteria for students
    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...
