You always raise the top of your range - that is, hands that have at least 50% equity against Villain's calling range.
If Villain folds too much to a reraise, then, in general, you polarize your range. That means that instead of raising only your top hands, you split your raising range into some from the top and some from the bottom of your range.
The basic rule is that you estimate Villain's calling range, and you raise with all the hands that have 50% or more equity against that range.
Then you may find that you are still being exploited by bet-sizing, and now you're not raising often enough.
You need to add more hands to your reraising range, but you don't want to add the strong hands with less than 50% equity.
You want to add hands that you are happy to get Villain to fold, so you start adding the bottom of your range, as pure bluffs.
The only reason to NOT reraise QQ PRE is if you have a very strong read that Villain's calling range gives your QQ less than 50% equity.
I'm not going to bore you with the math behind the error bars on poker stats. It is enough to know that the error bars are going to cover a range of many %-age points. When you're looking at a very small number, like estimating a stat at 5%, the error bars are gong to go from like 2% to 9%.
Meaning that even if the shown stat dictates that you may merely call with QQ, it won't be a "bad" play to raise with QQ, because the uncertainty you have in the shown stat is a real, verifiable amount.

Moral of the story:
If Villain calls a reraise with { JJ+,AQs+,AKo }, then you would have 48% equity with QQ.
If Villain calls any wider than that, your equity will be above 50%, and you should be raising QQ.
If NOT, then calling with QQ is prob. best.
