Hi, I really need help on my Math Studies IA. I am investigating the relationship between language ability (the number of languages a person speaks) and academic performance (their most recent IB grade) in Math and English. I want to see if there is a correlation between these two variables of language ability and academic performance, and later on compare to see whether language ability has a stronger impact on performance in Math or English. Can someone advise me the math processes I could use for this. I tried making a scatter plot but since both of my variables consist of whole numbers it isn't really working out.
