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

https://docs.google.com/forms/d/1KKZMguXKnIiGoeYc5XJfzZ9285sJzC5HoG6NWV9ocyI/edit HI everyone! I'm currently working on my math studies IA and I would really appreciate it if you guys could answer a couple of questions for the data collection! Thank you!!! (it's in both english and french)

I am wondering how the IA's will affect the final IB grade. Let's say I have an accumulated 4 on my Econ IA. However, I get a 5 on my External Assessments (all 3)! What will be my Final grade? Will it be a 5 or a 4? I know the IA is 20% and the external Assesment is 80%. I was told that whatever I get on my External Assesment, will be final grade. The IA helps if the candidate is at the very end of a boundary. I have been getting different pieces of information. I am not sure how the IA works. Everyone keeps saying its "Only 20%", and the External Assessments are far more important.

I am sure what I should do for my Physics IA. My question right now is "What is the relationship between the radius of the ball, the angle, and the distance traveled?". I feel that this question is to simple. I was wondering if anyone had any suggestions or other ways I can look at it. I am open to any ideas and I am still at the beginning so I can change it.

Hey everyone! I'm at the moment writing my History IA and I need some help. I really want to write about the Watergate Scandal (1972-1975) however, I've been having some trouble coming up with a research question. Do you have any suggestions? I thought of something like, "To what extend did the Watergate Scandal contribute to the impeachment of the former president, Richard Nixon?" However, I don't really know if it leads to an analysis since it sounds more like just finding facts and making a conclusion. Hope you can help!
