TypeError: NDFrame._add_numeric_operations..sum() missing 1 required positional argument: ‘self’
Please gives us a proper background of your query. Which course, week, assignment, and exercise? Post your full error (not code).

Hi @Bhagyashree_Hambarde! For the value of x you are in the right direction using the sum method. Notice that data is already of type pd.Series so you can call it directly as data.sum(). For p, you are getting that error because in the context of the dataclass x does not exists. What does exists is self.x but since you are not within any method that has self within its scope then it is also not available. You can achieve this by using methods but in this case it is way easier to duplicate the code for x and n.
