ahmed Posted October 3, 2016 Report Share Posted October 3, 2016 hi so iv been working on my math IA about studying and extrapolating the increase in population of canada and predicting the population in 2020 given the current data canada.xlsx right now i have graphed the function and the equation with R^2 value but im not sure what the equation means i have attached the file... any idea what to do Reply Link to post Share on other sites More sharing options...
IB Math Helper Posted October 5, 2016 Report Share Posted October 5, 2016 The equation tells you the population ( y ) at the given year ( x ). The co-efficients are rounded. You need to figure out how to get the exact co-efficients if you want to test the function for interpolation or anything else. Reply Link to post Share on other sites More sharing options...
kw0573 Posted October 27, 2016 Report Share Posted October 27, 2016 Without giving everything away, you may want to compare rate of population growth in Canada compared to a different country. Just briefly going over related topics is a geography book on population pyramid and natural growth rate will prove to be very beneficial. How is your model of population growth reflective of the demography (or even policies) of Canada? At the SL level, most correlation topics can be readily be modified to become much more advanced than a Studies IAs by offering justification and evaluation of the curves of best fit.

IB Math Helper Posted October 28, 2016 Report Share Posted October 28, 2016 Also consider things like immigration, natural birth rate, death rate etc. Basically if you dig in deeper into the components of what makes the population grow, which of these components dominate? If you can decompose your population function into other components (e.g. immigration + birth - deaths etc) it will add more your IA. Reply Link to post Share on other sites More sharing options...
