Pokemon Question (Ghost and Dark)

Hey it's this kid's brother again.

Now i have been playing pokemon since i was about 9 years old. (The year red and blue came out) And now i have a question that has been bugging me for awhile. Its with the types Ghost and Dark. I don't know they are in the the Spec. Attack section or the Attack section, I'm pretty sure Dark is the Attack Stat., but I'm not sure about ghost becuase it seems like the new Ghost Pokemon have high attack and low special attack. Could you clear things up for me? Thanks

Actually ghost is att stat and dark is sp.att stat.

And im 101% sure btw :P

Thanks, it always bothered me because it seemed to criss-cross all the time...But why does shadow ball have a chance of lowering Spec. attack if its a attack type? That doesn't really make sense, but i guess the stats of the pokemon don't lie.SUB-ZERO999
