As they say, a picture (or a video, in this case) is worth a thousand words. The video here shows one way to use the spreadsheet on the TI-Nspire... more

    Sure, I get that. But box plots are not explicitly listed in prior learning topics or in 5.1. That's my issue. I guess you could interpret "display of data in pictorial and diagrammatic forms" as including box plots.

    Daniel, Thank you very much for your feedback. For the 4 'accessible to discriminating' questions above, I can see how the wording is not real clear for Q.2. I've changed the wording to try and make the set up of the diagram more clear. I've...

    I used a couple of these questions with my students who are revising for their exams and came across a couple of typos/errors. In question 2, the minimum time would actually be walking along the road the whole way (2 hours v. 2.07 hours with...

    That's one of the tough aspects of IB maths exams - they are unpredictable. Which I think is a good thing, because it requires students to do some problem solving and strategizing - and not just answer routine familiar questions. There was...

    Thanks. I'm just looking at what to include with my current HL cohort at the moment. I'd say box plots are fairly unlikely on a HL paper also, correct?

    Hi Benson, It's possible there has been in the past, but personally I do not recall an exam question with a frequency histogram having unequal interval widths. It's the kind of thing that I cover if I have a little extra time b/c it can be...

    Hi Tim, has there ever been a question on a HL paper about frequency density (ie histograms with unequal class interval widths)? I can't find any on Questionbank.

    Sharma, The start-of-course assessment and algebra refreshers could certainly be used to help a teacher determine if a student is properly prepared to be successful at HL level.

    Can we use this assesment and refreser for HL / SL selection

    Sandra, There is certainly no need to cite every formula. Where I think it is important for a student to provide a citation is when they carry out some mathematical working that they did not completely figure out themselves. If they use an...

    Thank you :) Another question... Does a student have to cite every formula he uses? Even if they were taught in the lesson or are in the booklet?I assumed not, but now I am not confident enough about that. Thank you!

    Sandra, Good questions. Yes to both. Moderators expect to see written comments by teachers on the student Exploration providing some rationale for marks awarded for different criteria. Also, moderators like to see a checkmark next to students'...
