leviosa Posted November 30, 2016 Report Share Posted November 30, 2016 Helloo I had an idea for my sl math IA topic but wanted some input on whether or not its doable/appropriate before I hand in my proposal. So I was planning on exploring if there is a correlation between a country's Gini Coeffcient ( http://www.investopedia.com/terms/g/gini-index.asp ) and their overall stock market trends. Let me know what you think, I need any and all advice! Thanks in advance Reply Link to post Share on other sites More sharing options...
IB Math Helper Posted December 2, 2016 Report Share Posted December 2, 2016 What do you mean by "overall stock market trend"? If you're doing a correlation between the Gini-coefficient vs "overall stock market trend", you need a number for both. For example if you take a country like Finland, its Gini co-efficient is 0.271. However, what is it's corresponding "overall stock market trend"? This trend is not a number and therefore cannot be plotted on a graph and consequently the correlation co-efficient between these two variables cannot be found. A different variable to use might be the country's GDP in a given year. This is a fixed number and thus can be plotted with its respective Gini co-efficient to find a correlation co-efficient. Hope this helps. Reply Link to post Share on other sites More sharing options...
