    Hey, so my math teacher gave the class our IB project which is due before christmas which is on the Population Trends in China, but when I look at it I haven't the slightest idea what to do. I was wondering if you guys know any good websites which help with it or perhaps if anyone's done it at all? Thanks And just to clarify im not looking to copy or anything just advice and tips

    Is this about specifically modern population trends or throughout history? Peter Turchin has done a good bit of work on statistical modelling of long-term population trends in China, so if you look that work up on Google you might find some ideas.

    Don't worry - this portfolio is not difficult! Just read the assessment criteria thoroughly. This is a summary of the portfolio:

    Introduction
    Plot data and define parameters
    Comment on any trends
    Suggest and functionS(!) types that could model the trend realistically.
    Develop ONE model by using math and reason. (I found it graphically and THEN went the other way... But don't let that show!)
    Plot model with data, and comment on fit and revise.
    etc. Its on the sheet.

    If you think about it, how is the population likely to develop? Exponentially until infinity? Or would it go up and down? Linear? Curve? Limit? Quadratic? There are several options, some more realistic than others.

    To interpret K, L, M - look up logistic function on the Wikipedia, and ecosystems.

    Make sure you apply the best fit model to other populations as well to test it's validity:-)

    I hope this helped!

    Edit:

    You barely have to know anything about china, its the ability to model that is really assessed. I mentioned the one-child policy once, I think and my teacher was really impressed still.

    don't worry mathematical population dynamics is one of my interests - just PM if you need to know anything

    so, I cant even start it. I'm such an antitalent for it!
    if you are already done it would be cool for me just to review t and then I'll realise my own and be able to do it in my own way (no plagerism, no worries)

    would it be fine?
    I will write me email adress in next comment

    no no no I haven't done this particular project I just know a lot about population dynamics. So I will be able to help you but only with the general modelling principles where to start etc

    You shouldn't simply ask for a copy of somebody's work - have you not heard about the IB plagiarism rules and penalties?

    Plot the given points on a graph - do this by hand or via TI-84 or equivalent.

    What type of graph do the points seem to lay on - linear? cubic? Choose the one you wish to develop and analyse it using the TI-84's regression program. Draw the regression line on your graph of the original data and comment on how well they fit. Mention also the regression coefficient, r, which should have been given in your calculator read out.

    This should get you started.

    I've developed/analysed a cubic model using algebra, matrices, RREF etc.
    Firstly, is this realistic? Could it work?

    Secondly - I haven't heard of regression - could you briefly explain what it is and how it relates to this?

    Thanks
