I watch a lot of anime, and what I have noticed is that for sentences in English where you would normally say "No", they use ちがう, which I understand the best translation is "wrong". Which is fine, but then where would you use いいえ? I actually almost never hear the use with いいえ.
Same thing with 何で, which I hear all the time as "why?", but never どうして.
