One can conduct a two way anova analysis for this purpose with response variable as marks and row factors as different levels of study hour in a day(i.e 1 for 0.5-2 hours,2 for 2-5 hours,3 for 5-8 hours and so on.) and column factor as number of participation in different co-curricular activities(i.e 1 if the student participated in one co-curricular activity,1 if the student participated in two co-curricular activities and so on)
