For the Math Studies IA the student is to pick 2 variables they believe are related to each other in some way and test this using statistical analysis calculations. You can literally pick any two variables. I for example chose how many hours people play video games on average per week and the amount of words they could remember in a 1 minute interval. You want this to flow like a story, no one wants to grade something where you just throw numbers at them. Explain what they mean. Explain why you did this (I don't care if it's simply saying you simplified a fraction, do it). I'm not saying the graders suck at math, I'm saying that you don't know who's getting it so assum…

I am doing my Maths portfolio on investigating divisibility atm. I am really stuck on question 3 and 4. These are the portfolio questions 1. Factorize the expression P(n)=n^x-n for x = 2,3,4,5. Determine if the expression is always divisible by the corresponding x. If divisible use mathematical induction to prove your result by showing whether P(k+1)-P(k) is always divisible by x. Using appropriate technology, explore more cases and make a conjecture for when n^x - n is divisible by x. 2. Explain how to obtain the entries in Pascal's triangle...State the relationship between the expression P(k+1)-P(k) and Pascal's traingle. Reconsider your conjecture. Write an express…

My Math Studies class is a huge joke...I use it to catch up on homework, never paying attention and I ace every quiz. It worries me because I only found out recently that MS is generally looked down upon...do colleges take it into consideration when look at applications? I'm not a Math student in any way, my best subjects are History and English. However I think I'm pretty good at it. Do I need to worry about this? Should I take Pre-Calc Senior year or maybe go one step further and take Pre-Calc over the summer/in my free time so I can take Calculus next year?

This IA asks to develop a probability density function (pdf) for the chart described below. I'm stuck at the question which says "Add two other columns to the chart, entering the excpected frequencies for the 1000 saplings for both normal and Poisson distribution. Test each as a possiblemodel for the data" The chart is:[Height of saps in m],[Frequency] 0.00-0.25 , 61 0.25-0.50 , 160 0.50-0.75 , 209 0.75-1.00 . 202 1.00-1.25 , 158 1.25-1.50 , 105 1.50-1.75 , 58 1.75-2.00 , 29 2.00-2.25 , 12 2.25-2.50 , 4 2.50-2.75 , 1 2.75-3.00 , 1 I have a problem with the Poisson distribution, what am I exactly supposed to do?

Hi! I just checked an old Math Studies test and there they tell me, at the first question, to find the Standard Deviation... However, the question is only worth one point which for some reason got me to think if the effort I would have put into it really would have been worth it, and I thought, perhaps there is a quicker way to gain Standard Deviation than I know of? Because the way I do it is tedious. That's why I ask you, is there a quick way of finding a Standard Deviation?

This might sound like a silly/basic question to many, but I'm anything but bright in maths. As much as I try, and despite the fact that I've tried reading from various books, I cannot for the love of God understand perfect square factorisation. Apparently, there's an easy way of solving it with the GDC. Can someone please explain both methods, with and without GDC?

Hi, I'm currently at the end of my first year in IB and possibly be predicted for a grade of 27 only! All because of Math and Physics(not really important at this thread). I originally chose Maths HL but soon downgraded to Maths SL and now I'm thinking of Math Studies. I'm just not good with numbers as in any other subjects I excel in it e.g English or Geo or Business. I chose Maths SL to ensure my choices aren't limited to only a few choices(University courses). I'm only really interested in the following courses: - Business Management - Finance and Accounting - Geography/International relation - Politics/law Thank you,

Hi! I've been wondering for some time now, for the past few months I suppose, if Studies would be more beneficial to me. I've had 2 math mocks now: I got 3 from the first one (Statistics) and now 2 from Calculus. When I attended junior high and pre-IB, I felt that I was at least mediocre. I got 7s and 8s from tests (on the IB scale, that'd transfer to 4s and 5s). Suddenly, on my first IB-year I've become real bad at math. I know how to solve the exercises during the class - even the exam style questions - but somehow I don't know how to solve the exercises we have in our mocks My current subjects are HL Bio HL Chem HL Psych SL Finnish SL English SL Math and I'm still…

Ok to start off my math teacher is horrible she has not given us anything to prepare us for the IB exam. We don't even know what is going to be on it or anything; that’s just a little background information. So recently she has given us our project information and hasn't told us anything but its something we have to do ourselves and that we need to investigate something that we can write up. Well I decided to use the average Body Mass Index, height and weight of teenagers and compare them to my high school track team. After I have decided if they have a normal, under, or over BMI then I was going to compare their athletic abilities. But I have no idea how this is to be or…

Okay, first of all i've read alot of forums concerning about math studies "worth" and there are so many like clashing opinions that i don't know which to believe. so, people have been saying that taking maths studies would hinder your chances at uni, but some say that it doesn't matter if you took maths SL or HL or what but what really matters is your over all garde in the ib. i saw this one person saying that there was this girl that took art and maths studies and business and got a 42 in her ib grade but is still accepted in a college with a scholarship. so really, coz i don't know where to go. some say, take SL atleast (im in studies now) i got a B in my gcses higher.…

Alright, don't laugh... I've been struggling in IB math studies. I got a 2 in my math exam for grade 10 and upon being recommended to do studies for IB I STILL got a low mark on the final exam. I always did the homework, payed attention in class and thought I'd grasped the concepts and would be able to use them but whenever it came to a test I rarely did well. Does anyone have any advice on what I can do? Like a guide or advice on studying? Honestly, anything is welcome.

So basically all I need is: Your name (you can make one up if you must) Your taste in music (please do not give artists, just genre and try to stick to one genre - I can only use one) Your predicted IB grade (EXCLUDING EE and TOK - If you have it ) Thank you so much lovelies

So, I took a math test last week. I am getting my results back on Monday... Regardless, I already know my grade due to my school's managment system I scored a 17%. Yeah, its not a typo, or a mistake. I scored a 17%. I flunked and I knew I was going to flunk while I took the "Quiz" (which he later on revelead to us was a Test). I can proudly say I did not study at all, this is my third week in IB SL Math and my teacher just sucks, everyone is complaining about him constantly and well, my class was going to uproar against the teacher and impose him to drop our low grades (ranging from 17 - 69). Until I recently found out that someone in my class got a 91% My hopes are ruin…
