    Scattergraphs - 15 Countries
    Hi Ewa - I have fixed this now and taken the opportunity to revamp the two pages a bit. Thanks so much for pointing it out! Interestingly enough, when I compare some of the graphs I get now to those from when I made the activity there are some...
  • Wow Ewa - that is quite an important mistake. I am trying to figure out what country I had there instead.... Thanks for spotting, i'll let you know when I have fixed it, Thanks, Jim

    Marking & Moderation
    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.

    Me too. I was going to try another browser. But there are a number of references to videos that I can't see.

    I'm not seeing any videos on this it because I don't have Cabri Geometry?

    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...
