IA IB help me! please :)

What topic/equations would I use for a correlation based IA? FYI my title is "correlation between length of day and time of year" ...Thanks!

[Rigel]

Mhm? I guess the topic is obvious and not so interesting to make some research about (in January the days are shorter, in July the days are longer?), and if there's a relationship, there wouldn't be too much mathematical content on it. Why don't you try to do some modelling instead of "more complex" phenomena or topics that aren't too obvious but are still in range of the Math SL syllabus?

This depends on whether the OP does Maths SL or Maths Studies. If its Studies, it's still not possible as the idea of the IA is to gather 2 sets of quantitative data and use various mathematical calculations. Months of the year wouldn't work as it isn't quantitative. For example, for my Maths Studies IA, I wanted to establish whether there is a relationship between the budget spent on a film and its gross income.

If that's what I'm explicitly saying (isn't modelling phenomena trying to gather 2 sets of quantitative data and use "various mathematical calculations"?). And isn't it too vague to just model or correlate random data and come up with a general conclusion? Or perhaps, that's what the Math Studies IA is asking for.

Perhaps I should have explained a bit better. These "various maths calculations" are step by step calculations which are done in order so as to enable the student to form a conclusion in the end. I can't remember how I did it exactly, but there were calculations for standard deviation, chi squared test, regression line and a lot of other things too. And the data isn't random, you have to collect data either from a secondary source (I got mine from the internet) or you carry out your own research, but you need a minimum of 80 sets of data in order to carry out an efficient experiment. In my case, I found the film budget and gross income for 80 films and I used that as my data.

The point of the Maths Studies IA is very simple, it's just a research project based on whether you can find enough relevant data and carry out appropriate statistical tests in order to come up with a conclusion of whether the 2 variables you researched have some sort of relationship or not.
