Question

Which is a true statement about two numerical sets of data that have a negative association?

Answer 1

When we consider Linear Correlation between two numerical sets, there can be 3 possible relations

a) Positive Association
b) Negative Association
c) No Association

Negative Association or Negative Correlation refers to such a relation in which if values in one data set are being increased, the values in the other data set will decrease, resulting in a negative association. Such data sets always have the value of correlation coefficient between 0 and -1 i.e. a negative value.
