lynusrynu Posted November 30, 2013 Report Share Posted November 30, 2013 Hello! My IA topic idea is 'is there a correlation between goals the top 20 Premier League's season 12/13 players scored and their height?'What do you think about it? Is it good? My teacher accepted it, though I would like to hear some other opinion. Cheers,Lena. Reply Link to post Share on other sites More sharing options...
Guest Posted November 30, 2013 Report Share Posted November 30, 2013 It sounds like a topic that could work but I am confused as to what math you would use with this? Reply Link to post Share on other sites More sharing options...
Pierre Reynaud Posted November 30, 2013 Report Share Posted November 30, 2013 I think it's good topic ( I'm not a pro, soo don't take my words for it) you could use the Pearson's Correlation Coefficient and and the chi square test to prove it mathematically . But sounds good to me Reply Link to post Share on other sites More sharing options...

But sounds good to me Although I agree with the tests you mentioned, they won't "prove it mathematically". You have to remember that correlation doesn't mean causation, and this is one of the things you'll have to talk about in your conclusion. 1 Reply Link to post Share on other sites More sharing options...
lynusrynu Posted December 28, 2013 Author Report Share Posted December 28, 2013 Thank you for all the anwers!I have one more question- do you think it might be not enough? My classmates are making 100 people surveys, does IB prefer that? Should I add another league to my IA? Reply Link to post Share on other sites More sharing options...
lynusrynu Posted December 29, 2013 Author Report Share Posted December 29, 2013 what is more, even after dividing the data into 3 groups in the chi-square I have values smaller than 5. Which other tests can I use? Reply Link to post Share on other sites More sharing options...
