I am not familiar with the statistical terminology (My experience is restricted to Mathematics), and, I am not a native English speaker. In the course of translating an English academic paper, I ran into the term "Inverse Relation", and searches have suggested that what I am referring is, more specifically "Inverse Relationship" (Rather than "Inverse Relation" which has its own, slightly different, to my observation, characteristics.). I specifically approached your members and not the English Forum members in the belief that Statistics's notion of those term would leave no place for doubt.
First, the actual text I am trying to comprehend is
"...the results indicated that the inattentive aspect of ADHD was inversely related to the emotional clarity aspect of...".
I now understand that in such a relationship, the decrease (or increase) of the value standing for one variable is followed by the increase (or decrease) of the value standing for the other.
My questions are:
In the specific case in question, would it have made a difference if "Inversely Related" had been replace with "Negatively Related"?
Is the case above a case of Inverse Relation, or Inverse Relationship, assuming those two terms are not globally equivalent?
Is a given "Inverse Relation(ship)" "invertible", i.e. reversible? To be more clear, is an inverse relation(ship) between two variables independent of the order order of the impact?
