There is a popular belief that if you are good in English, you are not good in Mathematics and vice versa. This means a negative correlation, meaning, the higher your grade in English, the lower is your grade in Math, or the other way around. To prove that this is wrong, a Mathematics teacher gathered some data on the grades of students and came up with the table below: Student Grade in English Grade in Math 75 76 88 89 94 95 75 73 86 85 83 84 79 78 77 76 76 76 10 93 94 11 91 90 12 89 88 13 85 86 14 84 85 15 84 83 Is the popular belief correct or just a misconception?
