I have a data set where there are two variables X and Y, X being a set of values and Y being a set of corresponding values, like X = [1, 2, 3, 4] and Y = [100, 200, 300, 400].

Ideally I should have a directly proportional relationship. When X increases Y does too, and vice versa. What I would like to do is learn what might be the relationship, is it linear or non-linear or something else. How are such things explored?

More generic questi![enter image description here on when give two such variables how do you start exploring it? How to check if there is correlation?
