dimik 1 Posted October 3, 2020 Report Share Posted October 3, 2020 Hi, I am in need for more ideas about my Maths IA (Maths A&I SL). I investigate the relationship between sleeping hours and working hours. I already performed chi-square test, regression analysis and I created box n' whisker plot, but my teacher thinks that it requires further analysis. Thank you in advance!!! 😊 Reply Link to post Share on other sites
