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
Hey guys! I need help... For the Math Studies IA in criteria C it says that you need to show at least one calculation of each simple and further process BY HAND. I did the further process (correlation) by hand, but i have 80 samples and showing how to do average and standard deviation for the 80 samples would take up a whole excel page. Do i have to show it? How does it work? Maybe i misunderstood the criteria, please help!
