Florian Priv Posted January 1, 2013 Report Share Posted January 1, 2013 Hi guys please could you help me out hereI have chosen to compare people's foot length and their height in my project...but i find it near impossible to find maths I could use please could you make some suggestions?I thought about using a CHI test but then apparently that doesnt work with lengths and heights... is that right?Thank you so much in advance!

alefal Posted January 2, 2013 Report Share Posted January 2, 2013 (edited) You can indeed use the chi-squared test. Just make sure you use frequencies instead of the actual lengths and heights. Make intervals for the lengths and heights, and write down how many individuals fit within each of the intervals and put that into a matrix. Then you do the chi-squared test. Just make sure you don't violate the rules for the chi-squared test. You could also use linear regression and probability. Remember, though, that you have to use both simple and sophisticated mathematical processes. Edited January 2, 2013 by alefal 1 Reply Link to post Share on other sites More sharing options...

Thank you again! Reply Link to post Share on other sites More sharing options...
alefal Posted January 3, 2013 Report Share Posted January 3, 2013 You find the critical values in the very end of the math studies booklet. You need to find out the degrees of freedom, which is (rows-1)*(columns-1) if you don't remember Reply Link to post Share on other sites More sharing options...
