Low values vs Small values

I would like to describe the indication of some numerical index, let us say x. I would like to say that if x << n then this indicate positive impact however x >> n this indicate negative impact.

In such context, I should say :

"Low values of x indicate positive impact "

or

"Small values of x indicate positive impact ".

Which one is correct ? If both, which one is more suitable in my notion ( scientific one)? does it really differ if I use Low instead of small?

• What is the context of your index? Mathematical? Financial? Social? Commented Jan 26, 2016 at 10:15
• @Peter I stated it is numerical, in fact it is the outcome of a mathematical formula. Commented Jan 26, 2016 at 10:24
• @Nizar I think Peter's question is about the context of the formula.

• Did you mean to use the "much less than" symbol? (i.e., "<<"). If so, I'm not sure if either statement accurately conveys what you are saying mathematically. It might be better to say, "Values of x which are much smaller than n indicate positive impact."
