    Hi Jim, Thanks for the additional material on the IA, very helpful. I also liked this IA, clearly a student enjoying their work. Just a quick question on B. As there is no raw data included, would this limit the candidate to a 1 ? ,,,and what...

    Thank you so much for adding these, it is great to have some new examples to look at. I love this site, but I do have an idea for consideration and I am trying to do as well. I think it would help to do a "fake" IA with students with pre-defined...

    Hey Jim, So I love the blog, and my thinking is like yours; however I think that contradicts the IBO. In the examples they give if the r is low, they use chi. What do you advise students to do if their correlation coefficient is low? Here...

    Project Problems
    I am having a fundamental issue with part of this project. I get that when the correlation coefficient is low they should not go further to regression, but what I don't get is why and how they should do chi squared. I am teaching AP stats...
  • I am thinking of how to use this as a great way not only to summarize 1 variable stats, but to help with IA. Could they group them, how would they group them, why. How would we handle gaps and various years. What would be great comparisons....

    On the presenting the functions activity, The directions refer to a list of functions, but I am not seeing a list ...just making sure was this attended to be with the three major functions (linear, quadratic, exponential) or is this for them...

    I second the motion. It will really be helpful to see guide for Math Project focusing on calculus, trigonometry, volumes of pyramids and cones, exponential functions and probability.
