  1. Hey guys, My draft for mathIA is due in 1 week, and I have the topic but I haven't written anything. The reason is I don't know what to write about. I know I will be writing on the martingale method, and I have written a java script which simulates this method for 1,000,000 rolls of roulette on the American (double 0) roulette board. I can choose the initial bet and how much money I have at the start. Should I just write my IA on debunking the betting method? Or find the optimum starting bet based on the total balance? Or should I make a new betting method and write the cod

    Math IA Topic

    I’d like to do my Math IA on some ring music related, but I’m not exactly sure on what specifically. I’d like it to be relating to harmony or pitch but really anything involving music would be good. Could someone help me get some ideas?
  3. I have already written my Economics EE on what factors have caused public transportation ridership to decline in the US in recent years . My Math IA is currently on whether population density affects the ridership of public transportation in the US. As you can see, it is not the same topic but it is very similar and I was wondering if I was allowed to use writing from my EE (my own) and incorporate it into my Math IA. Would it count as duplication? Anything helps so thank you in advance.
  4. Hi, I was wondering if any one has any ideas for the Math IA that relate to scuba diving? I'm really struggling to find something... Or if anyone has done it in the past, what was your idea? Thank you!
  5. Hi, I'm supposed to be working over my math IA over the winter break, and I'm planning to do a stats IA to see the correlation between sleep deprivation and anxiety, since we'd be very familiar with the two things. By "anxiety", I'm asking specifically about feelings of worry, uneasiness, or nervousness to the point where it affects your ability to function. It can be anything from mild (ie: not being able to focus) to moderate (ie: feeling nauseous) to severe (ie: hyperventilating). So for the survey: 1. How many hours of sleep do you get on an average school night? 2. Do you experience any a

    Math IA

    Can data sampling and its effects on statistics be used as an IA question? Or is it too basic?
  7. 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.
  8. Hello, I have chosen to do my math exploration on Non-Euclidean Geometry but i have a hard time finding a specific topic to explore. I would love some help and ideas of problems i could solve. i have thought of showing that the earth is round and also doing something with GPS signals. I am really lost, i just need a path to follow. Thank you
  9. Hi, I was planning on writing my exploration on Fourier Series and its application in music, specifically maybe showing the function of the overtones?? idk because I can't seem to find any good source that would examine this and although I see the link between these topic, I still do not see really the way it intertwines and my deadline for the first draft is in 2 days:) did anyone do their exploration on similar topic? is it doable? are Fourier Series even doable for math ia? please help me
  10. Hey everyone! I'm currently in the period of time to choose my topics and making proposals for the Math IA and I'm currently choosing to try do a research on Badminton. I really love Badminton and have been playing it since i was a child so i really love it and i am very interested in it. But i need some help on ideas what i can do research in the ideas for Badminton. I hope that anyone can help me by giving a little idea or anything that can help me with my Math IA. I need help cause i'm not that great in Math. And i did found some relations between math and badminton.
  11. Hello! Recently, I have come up with calculating the volume and surface area of wine glasses for my Math IA (I am in Maths SL). I am just wondering whether if this idea is suitable for Maths SL and whether if it shows personal engagement. Since this idea would involved relatively more heavy calculus as I am at SL level, would it show personal engagement because I am attempting to learn something more challenging and outside the scope of the syllabus? In my opinion, it is not exactly unique or crazy creative compared to the sample IA's I see, for example graphing cosmetic contact lens patterns.
  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 scatte

    Math IA

    I have decided to have my Math IA revolve around the probability behind the prisoner's dilemma. I need help deciding on three simple maths and one sophisticated math to explain the game (besides a tree diagram and expected prison sentences). I am afraid that I won't have much numbers/math to work with. Thank you in advance.
  14. Hi all so I'm really desperate here 😓 I suck at maths and have no idea on how to progress my ia mathwise Basically my question - How can I minimise costs (expenses) in order to achieve a maximum amount of profit? (in a bake sale) I was planning to Find out the total cost of the ingredients ( with reference to the recipe from Joy Food Sunshine) Determine how many we need to break even (Break-Even chart) Based on break-even number how much ingredients do we need and cost Then find the ‘volume’ for the cookie dough and
  15. Hey could y'all please answer these questions? It'll only take a couple of seconds. Thank you Survey Questions: Male or Female? Do you play an instrument? What? Are you a part of an orchestra or a band? If yes, which one?
  16. Hi guys. I'm in my last year of Math IB (SL) and I'm in desperate need of some guidance. I have no idea how to go about doing my IA. I've decided that I want to find the optimal speed at which a vehicle (a tank specifically) should travel to get the best fuel efficiency. Along with this, I might also try and figure out the temperatures at which oil would freeze inside the engine by like graphing/modelling it somehow?????? As you can see, I'm really lost and I don't know how to approach this topic and I don't even know what math I should be using. Any advice on how I shou
  17. Hey, I need help with my Math IA. I am interested in Math and art topic to write about. More into the body proportions and how an artist uses it but I don't know what mathematics is behind it. What mathematics do I use to get a higher score?
  18. Currently, I am doing my SL IA for math this year, but I am having difficulty in collecting data for me to use in the SIR model. My IA is due in two weeks, and I still have not turned in my Data part for the IA, I really need help on finding websites that I could use in inserting the proper data for the model. Could someone please recommend a few websites I could use to find data for the construction of my SIR model? Thank you!
  19. Hey everyone, So I'm currently doing a practice math IA for maths SL and I need help! I chose the topic to do exponential growth and decay and I'm investigating the growth rate of bacteria however, I'm a little stuck. So basically, I've already got the formula for exponential growth of bacteria but that's pretty simple math and idk what else to do like do I just plug in numbers bc that's kinda boring and way too simple. I was thinking about investigating the effect of glucose-salt levels on E. coli bacteria to extend the topic but I don't really know how to do that and all the websites I'
  20. Hello everyone! As a part of my math ia, I am analysing the pharmacokinetic profile of a drug. A part of the pharmacokinetic profile involves finding the area under the curve of the medication's concentration - time graph. I think this area is meant to represent the total exposure of the drug to the paitent's body. This is what it says online as well. In other words, it would be the total amount of drug absorbed by the body. However, I'm not quite sure how this works, as the units used for the y axis (miligrams of the drug in each litre of drug - mg/L) are completely different from the x
  21. I really need some help rn. I'm thinking of doing a math exploration in the topic of Correlation between GDP Per Capita and Gini Coefficient in Countries. Basically, Gini coefficient is a measure of income equality in a country. The higher the coefficient is, the higher the income inequality. However, the mathematics skills & analyses I will use & do will probably only be from the topics of descriptive statistics and linear modelling. And so far, the IA samples I've seen with similar topics in correlation are only from math studies, so I'm getting concerned. is this topic to

    Math IA Help!

    Hi, so I decided that for my math IA, I wanted to look at the impacts of asteroids hitting the Earth using this website: https://www.purdue.edu/impactearth/ The idea I have is to collect different data like how big the crater size is and how it changes depending on the size or speed of the asteroid and more stuff like that. I then want to make graphs and find trends and see if these factors makes equations and stuff. I was also thinking that I could use the Richter scale to look at the intensities of the earthquakes and maybe show how that works. I don't know if this is very in depth and
  23. Hey guys, basically my math IA first draft is due tomorrow and I don't have a research question yet, my IA topic is on the math of figure skating and I am having trouble finding or creating a research question that shows the correlation between math and figure skating, my topic might have some physics but that's not the point, if anyone can help me find a research question for my topic I would be grateful. Thank you in advance. - Sara.
  24. Hi everyone! This is a survey for my Math Internal Assignment (for the IB diploma). I am analyzing how humans perceive beauty, specifically if people consider a face more attractive if it is closer to the Golden Ratio. It is a quick, anonymous survey which will take only a few minutes and it would be a great help to me! It took me a long time to edit all of these photos so I would be really grateful if you participated in it, thank you! Link: https://www.surveylegend.com/s/122r
