    Help with IA

    Hi everyone! I am a DP2 student and our Math teacher has started talking about our IA. My main idea is to compare acceptance rates of for an example, top 100 colleges in the US for Econ (which I want to study) and then compare it to the median salaries graduates get from those unis. I want to see if there's any correlation between the two in order to figure out whether I should apply for highly selective schools. If the correlation is not that high, then it doesn't really make sense for me to apply to them as the return will be the same if I go to a moderately selective school. I would construct a regression line and everything. My main question is - is this too simple of a concept for Math SL? I want to add a more complex concept that would fit in with the topic, but I can't think of anything. Do you have any ideas that might help me? For an example, I thought about constructing a utility value curve or something, but after discussing it with my teacher, we figured that it wouldn't work. She suggested constructing some pie charts, but it sounds like that would be way too simple. I would really appreciate it if anyone could help me as this is due by the end of the month. Thanks!
  3. Would finding the surface area of a hyperbolic paraboloid surface be a good enough topic for Math HL IA? I figured that I could use a pringle chip as my main reference for measurements and I could evaluate on the different ways I can approach the calculation (i.e. instead of using hypothetical measurements to find out the a and b variables of the hyperbolic equations I could graph out the x,y, and z plane individually and find out the variables from there). This involves multivariable calculus which is a topic that is outside of the syllabus, but I'm afraid that it will be too short of an exploration as all I'm doing is calculating the surface area of the shape. If anyone wants to chime in and give any advice that would be greatly appreciated.
  4. Hi guys. For my biology IA topic, I decided to focus on genetics and the subtopic would be inheritance. I have a few ideas on what to focus on but I need to narrow it down. So here are some of my ideas: Investigate on genetic diseases. Find the correlation between the variables that led to a specific genetic disease. Investigate a specific gene that led to a genetic disease. Focus on dominant/recessive alleles and how they affect generations of families I was thinking to choose between with family genes or plant genes. What should I focus on? Hope you guys can help me
  5. Hi! Please help me! I want to do my Math IA on something involving Korea and/or K-pop!!!!! I have no idea if I am allowed though to use as I'm not even sure where to find info for!
  6. I'm in history HL in a very small class with a very under-qualified teacher, and if I'm honest, I don't trust his judgement on my IA topic. The topic I proposed was: "To what extent did the Battle of Stalingrad force Hitler out of Russia?". I've also been considering similar topics such as "How impactful was the outcome of the Battle of Stalingrad on Germany?" I am really interested in this topic (and the Wehrmacht's time in the USSR in general) but I don't know if this is too specific, not specific enough, overdone, or even viable as an IA topic. He sort of just said "yeah okay" without giving any criticism or really any comments with substance. Would really like some feedback ASAP, thanks!
  7. I am trying to do a Math HL calculus IA on the flute and my outline is due in two days. I started by measuring the distance to the first open hole for each note fingering and graphing it on the x axis with frequency of the notes on the y axis. This gave me a quadratic function that can be differentiated to find the change in frequency with respect to distance (df/dD). I was hoping the differentiation would be a bit complicated but it's just the power rule since I got a quadratic. I am now trying to use related rates to find another rate of change, but I can't think of one that would be relevant. I was thinking of doing something with the volume of air required in relation to the distance to the first hole: dV/dD = dV/df x df/dD However, this would be way too simple. The variables I could change include length of the tube, volume of air, embouchure size, air speed and lung capacity. If anyone can suggest a way to salvage this idea, I would appreciate it. If I can't find a way to make this work I will probably cry myself to sleep because it's the only semi-good idea I've had.
  8. For context - SL student Hi guys, my school just started the chem IA process. I have a few (rather weak) topic ideas for experimental investigations, but would prefer to do a database ia because I'm lowkey terrible at lab work. My teacher also hasn't really told us how to go about developing methodology and approach so I'm a little clueless. Any examples of database IAs I can view? Also, how do you go from the initial topic idea to developing a methodology and approach? Do you look for existing experiments and modify their procedures? Finally, is there anywhere I can look for topic STIMULUS? (not topics, I'm not that lazy, but interesting chem things that could spark some ideas) Any advice is much appreciated
  9. Hi to all! I have to submit my HL Math IA tomorrow (Hopefully I will get another chance to update the file), and I have two topics. One is Modelling climate change and the other is Fibonacci series. Idk which one to go ahead with and how to do the IA Please help! I prefer to go ahead with Fibonacci series since it is the easier of the two. I really really need help as to what to include in the IA. Also what format should I use I know this is super last minute, but procrastination got the worst of me
  10. I am thinking of doing my bio IA with something that involved enzyme activity (for example, testing how different factors affect its activity). However, I don't know what I would put as my personal engagement to this.
  11. Hi! My Maths SL IA is statistics/correlation based, where I see if theres a correlation between age and rankings given to the top 10 photos of a photography competition. I was thinking of excluding scattergraphs from my IA because constructing 1 graph each for my ten pics take up a lot of space. Plotting 2 pics on 1 graph is really messy too. 8/10 pics have no correlation, so including their scattergraphs seem kinda pointless. However, having a visual representation of my data will be nice, especially since I can do my line of best fit for the 2/10 that has correlations. i have chi square, pearsons and spearmans so far. Would excluding scattergraphs be detrimental to my ia? Thanks so much!!
  12. Hi everyone, My Biology IA is based on the rate of photosynthesis and I will be discussing about its limiting factors in my background information and their affects on the rate of photosynthesis. Most of my knowledge comes from IGCSE, or from an online teaching/textbook-course thingy called Kognity. Would that be citeable? As you can only access Kognity pages if your school as registered. An example Kognity page is this: https://isb.kognity.com/study/app/biology-sl-fe-2016/molecular-biology/photosynth-core/limiting-core/ Also, is this link citeable? Because its basically a document that outlines everything and there is no clear author/not sure if this is counted as an article/website/manuscript?? http://www.rsc.org/learn-chemistry/content/filerepository/CMP/00/001/068/Rate of photosynthesis limiting factors.pdf Any help is appreciated, thank you so much!
  13. I was thinking of doing my SL Math IA on the optimization of a rugby kick. This involves some calculus and conics. I was wondering if this is a decent math IA idea? Thank you!
  14. I'm done with my math hl ia but it involves a lot of 3d geometry and stuff. I think I want to write it by hand I have a very neat handwriting and I can also draw the shapes. Can I do that or would it effect my grade negatively?
  15. Can you do your computer science IA in any language? I asked my teacher if I could do mine in Python, and she said no. But I've seen other people online saying that they have written their IA in a language other than Java, like C++ for example. I would like to use Python as I find it much easier to read and write; plus I've been coding in Python for a lot longer than I have in Java. So if we can write the IA in any language, does it say that anywhere in the guide? Thanks for your help
  16. Hi! The Maths teachers in our school said for SL IA's, we could base our IA's on statistics and use formulas like Pearson's and Spearman's and Chi-squared (not in the SL curriculum but is in Maths Studies). However, they said we have to explain the steps of each equation, as in like why do you need to multiply d^2 by 6 in Spearman's rank. Is this really necessary for a 7? If so, how would you get sources like this that explain how equations are derived? Thank you!
  17. So I'm doing my bio ia on the effect of different concentrations of sulfuric acid on seed germination. It's been nearly 3 weeks and I only have data for the control test (spraying with distilled water), and very few seeds germinated for any of the other concentrations (0.2M, 0.5M, 1M, 2M, 5M). These few seeds that have germinated won't really have any effect when I do the means for the 5 trials of each. Is it ok if I have very little variation in my data? It would be like an average of 14 out of 20 seeds for the control test and then less than 1 for every other increment. Does this reflect badly on me in any of the criteria? Or should I try and 'manipulate' my results? I realistically don't have much longer to do the experiment as I'm running out of supplies and school is closed for the break, and my teacher wants the other half of this ia done as soon as possible. Is it worth faking my results or should I just be honest?
  18. Hi! So I'm doing my internal assessment of finding an optimal route through some points of hte city using the Chinese Postman Theorem. My math teacher says its okay, in fact, he suggested the idea of doing this IA. But I have half of my work now and I think that the math that involves are very easy, so I'm scared that I don't get a good mark because of that. I'm doing the option of calculus, and this is part of the discrete mathemtics, so it's part of the HL syllabus, but do you have any suggestion of how can I do my IA a bit harder? Or do you think it will be enough? Thank you!
  19. I thought of the topic, "How easy is it for tourists to navigate through x city." Is this topic suitable? I wanted to do something related to public transport, but my teacher said that it is way too general. For the topic above, I could look at factors such as how many bus stops there are, train stations, taxi (and pricing), street signs, etc. Thank you!
  20. heya! I thought of doing my IA on the effect of caffeine on plant growth. Is this topic good enough? Any other suggestions anybody?
  21. Please could guys take this survey so that I can get enough data for my Math IA? I already have 24 responces and I only need 50. It is very quick, only four questions and it is basically how many IB/AP classes you take and how much sleep you get per night. https://goo.gl/forms/JIJQmFDp40hUYepq1 Thank you guys so much I really appreciate it.
  22. Hello, I'm a year 2 Computer Science HL student and just selected my idea for my computer IA. I have a doubt on whether the option we chose determines the programming language used for the IA. In my case, I have chosen Option D : OOPS concepts . So does this mean I have to use Java learnt from Option D for my IA or am I allowed to use other languages like C++ using Visual Studio? Thank you so much!
  23. I'm in physics HL and I have to do my IA soon. I found this interesting equipment in my laboratory that launches metal balls with a set speed or launch angle. I wanted to do something with this equipment and came up with the topic of comparing "launch angle vs horizontal range." I'm worried if this is too easy for a physics HL student. My teacher said it's better to stick with an easy topic and do the writeup extremely thorough. If this is too easy, I'm also considering to compare "launch height vs horizontal range." Could you please recommend which would be a better topic, and if both are too easy, could you please give me some inspiration for other experiments that could be done with this equipment? Thanks.

    Medical Math IA

    Hey guys! I'm looking for a math IA topic along the lines of medicine! I feel like the topic of the spread of infectious diseases is extremely overused and that maybe there could be a spin on it I could look at? Maybe somehow using statistics to find the most or least susceptible countries after findng the spread of infectious diseases? Also is there any calculations that could be done for some sort of bacteria immunization and how anti-biotics work to find out estimations of when antibiotics stop working for that bacteria? I would love to a medical math ia and any help is appreciated!
  25. I'm writing my first IA draft and I realise that I am very wordy, or maybe I'm putting too many details in but I've only done my introduction and social factors for my STEEPLE and I am now up to 1034 words..? I'm thinking of just doing a PEST analysis instead, but I still want to do my SWOT analysis. So my questions are: 1. Do words count if they are in a table? 2. Do I need to define what a PEST/SWOT analysis is before getting to the details like we're supposed to in exams? 3. Is it bad to be citing information and statistics from a lot of other places other than the supporting documents that you're including in the appendix? Is it bad to be having so many supporting stats in the first place? It feels like most of my 'commentary' is mostly describing what the market environment is like, accounting for why it's like how it is, with a tiny bit of "so what" at the end. Again, just based on my social factors. I kind of want to paste that para here to ask but that'll prob bite me back later...could I pm somebody? 4. "Will the implementation of localisation strategies be enough to allow Airbnb to circumvent the threats that the Chinese market poses?" Does this sound like a rhetorical question? My friend says it sounds like a rhetorical question T.T How would I make my RQ sound less like a rhetorical question? 5. Could I just exceed the word limit for the 1st draft cuz I get super attached to my words (this is semi-rhetorical hah =l ) Thank you! (pandas are soo cute <3)
