rue saint-denis Posted January 14, 2009 Report Share Posted January 14, 2009 Would doing an analysis of variance qualify as the required stats part for the HL IA? Reply Link to post Share on other sites More sharing options...
Zasxee Posted January 15, 2009 Report Share Posted January 15, 2009 I don't think so; my teacher made us keep it rather simple I could be wrong, as I'm not 100% sure; it may depend on the school, teacher, etc. Reply Link to post Share on other sites More sharing options...
rue saint-denis Posted January 15, 2009 Author Report Share Posted January 15, 2009 I'm not sure that I can do any other statistical analysis other than the ANOVA or a t-test with my data. If it's too complex, even more of a reason for IB to accept it, no? Reply Link to post Share on other sites More sharing options...
Graeme Posted January 21, 2009 Report Share Posted January 21, 2009 Rue, off the top of my head I'm fairly sure you are required to do "simple" stats. I needed to use the Kruskal-Wallace test (basically Mann-Whitney, but with three variables rather than 2). In the end I did 3x Mann-Whitney (to compare all three variables) and then did the Kruskal-Wallace as extra to show off. Reply Link to post Share on other sites More sharing options...
heartworthy Posted January 27, 2009 Report Share Posted January 27, 2009 definitely don't leave out any complicated stats analysis you can use, but like Graeme did I would suggest putting the simple ones in there too just to keep IB happy; for you it sounds like this would be a t-test Reply Link to post Share on other sites More sharing options...
rue saint-denis Posted January 29, 2009 Author Report Share Posted January 29, 2009 Can I include other data that I did not collect for comparison purposes? (like in biology) Reply Link to post Share on other sites More sharing options...
