  1. Hello i've decided to do my math ia on finding the length of a curved road These are the steps i need to follow to find the length of the road : Find the road on google maps Find a curve that fits the road but i don't know ho to fit the curve into the road by polynomial regression and matrices next i need to find the arc length through calculus does anyone knows or ever did a math ia on the topic pls reply im in dire need of help idk what to do here's a link to a file explaining the steps to find polynomial regression : http://web.iitd.ac.in/~pmvs/courses/mel705/curvefitting.pdf i dont understand the part where the person mentioned about least squares approach regarding polynomial functions and how she derived the formula
  2. Hi, I need to find ideas for my MATH SL IA and want to do Probability. My 2 ideas are either Probability in testing in medicine (false positives). Problem is I don't know what to do with the idea (what math to use) Normal distribution (any topic, just measuring distribution). If you could help me with ideas on any of the two as in what topics to include to get the highest grade I would be thankful. Is it enough to do a Chi squared test, normal distribution graph and use the equation? (for Normal distribution idea) Please I need urgent help and thanks

    Maths SL IA

    I AM PANICKINGGG!! I thought about doing my IA on modelling a rollercoaster but I am not sure on how to approach it and how to use good enough math on it. Maybe polynomial regression. Any other good ideas for a Maths SL IA???

    Maths SL IA

    Hi! I am thinking on doing my Maths IA on modelling a rollercoaster. I do not know how to approach this topic or how to make it personal. Any suggestions?
  6. Hi My math SL IA is the correlation of a country’s health care spending and its rate of tuberculosis. I feel like this doesn’t have enough math. Is there any way I could add more math to it.
  7. I've started my Math SL IA (finally) after not being able to find a topic for months, whatever I found I either didn't understand, was too simple, or my teacher said there was too little math in it. Currently, I'm working on an IA on the Tower of Hanoi, which happens to also be in an IB sample IA. I'm using the same aim and methods in the sample, but I am planning to cite the sample in my references and use my own words and personal engagement. I told my teacher about the similarity to the sample and she approved my topic, but I'm worried I'm plagiarising and will be penalised for it. Is this plagiarism or can I just continue with what I'm doing?
  8. Hey everyone, my IA is on basketball, specifically seeing if there is a correlation between the wingspan of a player and their career 3 point %. Ideas I have right now for the math in relation to this topic however are really thin. I pretty much only have the correlation between them using the r value. I've been stressing out about this a lot as this is definitely not enough math to get a decent to good mark on the Math SL IA. Does anyone have any suggestions for further math I could do with this topic? Thanks!
  9. Hii, I have a math test in 2 days and I really want to practice the may 2019 questions but I can't find the papers anywhere on the net. Can someone please help!
  10. Hi, I need an urgent help for my math IA. I have the attached graph, for my set of data. I need to find a suitable function for it and I really cannot find correct one. I tried to split the graph to different parts but the teacher said it won't be good. Therefore, if someone knows how to find a function for this graph I would be very thankful. Thank you in advanced :)))
  11. Im planning to do an IA on creating a model of female BMI from age 0 to 20, is creating model and finding out the sine equation enough? If not what else can I do? Thanks guys.
  12. My math IA is due soon and I was going to focus on weight vs. heigh of jump (grande jete) of ballet dancers. iw as going to take my data from famous dancers and analyse the videos in LoggerPro but I realised that I don't know the scale of the video and each dancer is a different distances from the camera. What should I do? Another idea I had was to look at the height vs. flexibility of a dancer and I could collect the data myself by getting dancers I know to do "sit-and-reach" tests. I would then find the minimum, maximum, median, lower and upper quartile, and IQR. Then I would create a scatter plot and a cumulative frequency curve. Is this complex enough for a Math SL Ia? Please help!!!!

    Math IA

    I really really hate math. I am terrible at it, but I just had to take math at school. Therefore, I have to do IA. What is the easy topic for IA in math? I want a good grade in it. The full score is 20, right? Please help. Any ideas?
  14. Hello everyone! Right now I feel that I reached my lowest point in my life. I am failing IB, and generaly feel so depressed. In our school we have marking 3 periods and end of year examps which count like a 4th marking period. Im finnishing IBDP yerar 1 and my grades wouldnt be worse: marking period 1= 24 points, marking period 2= 27 points and marking period 3= from my aproximate calculations i figured I wouldnt recieve more than 22-23! The subjects that i take are: Biology HL, English HL, Psychology HL, Chemistry HL, Math sl, French sl. I struggle mostly with math and CHEMISTRY (I HAVE A HORRIBLE TEACHER WHO DOSNT EVEN TEACH). I dont know what to do... I WORK REALLY HARD, tutors and past papers but nothing seems to work for me, idk. Please suggest something to me, a technique or options for universities that I have a chance in.. Also what is the outcome of these grades? How are predicted and real ib grades calculated?
  15. I am in semester 2, year 1 of IB, what is a good daily study plan for someone aiming to get a 45/a good IB grade? Is it okay to focus on one subject per day or to divide them within each day? Can I know anyone's IB schedule?

    Math IA Help!

    Hello! I want to make an IA on the carbon dioxide emission in my and one neighbor country. I will make the best corresponding functions for them and then I will connect my results with the population in those states. So I will find the correlation between emission and number of people, conclude and predict the future outcome. Is this ok? Could you suggest something?
  17. I'm doing correlation on the average hours spent in a week watching anime and the performance in English subject but I can't find any other extra mathematical matters to explore. All I have is only the correlation kind of formulas which is not enough for a math exploration. I'm desperately in need of ideas .Help!
  18. I need some more responses for my Math IA, so I would really appreciate if you would quickly fill out my survey: https://docs.google.com/forms/d/e/1FAIpQLSe7IuEph8ScgYcmxBfkcb0tid41fV1i1mycGQ-WJdw5q2s2Zw/viewform?usp=sf_link Thank you for your time!
  19. Hello! I am a French student doing the IB and I am doing a survey to complete my math studies IA. I would really appreciate it if you could take the time to answer my survey. https://goo.gl/forms/KIMSFSzwaWuudcPz2 Thank you, Thibault
  20. 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)
  21. Hello all, I am currently in my second year of IB and take Math SL, Physics HL, Chemistry HL. Due to a change in my major of interest I would like to take engineering in the UK but can't satisfy the Math requirement, would I be able to take a foundation year in the UK with these subjects and take my preferred engineering course upon completion? Also, should I retake the IELTS as I haven't done the UKVI IELTS but got an 8.5 on the academic one. Thanks!
  22. Hi! Having completed Math SL and scored a 7 on the exams, would math HL be an okay transition in terms of difficulty/understanding concepts?
  23. Hi guys, As I want to study economics at a selective university (in U.S) in the future, and I cannot stand taking Math HL at the moment, would it be sufficient to take Math SL combined with AP BC calc? I find Math SL very easy and score 6's/7's frequently (this is since I am repeating one year of the IB), so how hard would it be to shift focus during IB (repeated) year 1 and really study BC calc for almost a semester to take BC exams in spring? In this way I can compete with stronger applicants without having to struggle through the other than calc material in HL Math? Thnx
  24. Hello all, I'm in the process of selecting my IB courses for the next 2 years. I'll be completing the full IB at an established IB school so I have quite a few options. I'm interested in studying law or a social science at a UK university such as Oxford, or King's College. I think I have narrowed down my IB choices to the following: English A Literature HL History HL Economics/Business Management HL ESS SL (I know this is a 'soft' subject but I'm not a great science student!) Math SL Spanish A Literature/French A Lang&Lit SL What do you think about this subject combo? Do you think it's too hard, too easy? Also, do you think it's good for UK entrance and for the courses I'm interested in? Any advice would be greatly appreciated! Thank you
  25. Ok so like if I get a 7 on the SL math exam and i only get a 1 on the exploration/ia, what would my final mark be approximately???
