The question is not as easy to answer as it seems. Like sadolite says, there are some monsters out there, making our star a speck. BUT... Triangle.128k notes that most are red dwarfs. I think its noteworthy that using any scale, our sun is not very special.
@TBR Yeah but I chose large because the sun is a lot bigger than the majority of stars. The giants that are millions of times it's size are very infrequent. They do stand out however, given they can outshine millions of smaller stars around them. (Probably the reason why the milky way has a blu-ish tint to it)
It really depends how you interpret the question also, but you can compare it to wealth in at least developed countries. Lawyers are pretty rich, they're much more wealthy than most other people. But, their money is dwarfed if you compare it to a few million/billionaires.
@sadolite - Averaged on what? The red dwarfs (old) as they are now? How big they once were? Out of the total number of stars that we know, where are we RIGHT NOW, about average, or larger than average.
My normal way to average would be taking all the stars diamater adding it together and dividing them by the count of the stars. In this respect our star is much smaller due to how enormus the red giants are
