Hi everyone. I'm having a little trouble with my Math IA., I would like to do the topic "The Mathematics behind Medical Testing", where I would speak about false positives / false negatives and the probability of getting them. However, I don't know where to get data from. Am I supposed to make up a hypothetical situation / disease and then make fake numbers for it ? Is that even allowed..? I would be using conditional probability to find the probability of a student testing positive for the XYZ disease, actually having the disease. I would be using the conditional probability

Hi! So I've reached the end of the Pre-DP Program, and I'm constantly thinking of real IB. I honestly don't have any idea of what to expect for my next two years in the IB Program and that's why I've turned here. I was hoping for just a general idea of what the program is like in comparison to the Pre-DP program, and what I should expect? I also would like to know what school supplies I'll need. Is it the same general stuff I used in Pre-DP? What size binders do I need? Things like that. These are the classes I'm taking by the way: - HL English - HL Psychology - HL History of the Americas
