variability + singular or plural verb


The sentence is

Variability in data is considered a nuisance.

Variability in data are considered a nuisance.

Initially I thought is was the correct one, but it was corrected to be are. I want to know the reason.

2You were right. Is is correct. "Variability in data" is taken as a whole to be a singular subject. – Jim – 2014-08-06T01:33:03.097



The first one is correct, and the second is incorrect. "Variability in data" is singular, and "is" is the correct form for singular, not "are".

Your second question, why someone else wanted you to use "are", can only be answered by that person, I think.
