It's a pretty tricky thing because they give you a lot of reasons to believe that she's Yang's mother or sister. It depends on you which one believe:


 * Yang just talked about her mother a few episodes before her encounter with Raven so you could say it follows the plot. However, this applies for both the secret twin sister or the mother. Since the animation makes people look younger than they really are, Raven could be both her mother or sister based on appearance.


 * Not only her name has a similar meaning to Qrow's name but she also has the same last name. This could mean that Yang's mother is related to Qrow (sister maybe?) and she named the twin she took with her while Taiyang named the one he kept and that's why Yang and Raven have different names and last names. You could also explain it with the theory that Raven is Yang's mother and like Ruby and Yang: She was in the same Team as her brother. However, if this is true then that means Qrow and Raven are twins or one of them was also a prodigy like Ruby and skipped years. I feel like the twins theory is much better but at the end, either Yang and Raven are twins or Raven and Qrow are twins. Pick one pair.


 * The soundtrack. That music heard while Raven is leaving after she saved Yang sounds very warm and comfortable. Kind of like family. But saying it sounds motherly is a little too much since most fans also consider the songs Gold and All Our Days as Yang to Ruby songs. It would mean that most fans also think that music sounds sisterly too.


 * The combat abilities. This one goes more to the mother theory than the sister one because one of the strongest figthers in the series was defeated by an enemy who ran away as soon as she made eye contact with Raven. Either Raven has been training since very little or is a prodigy in combat. But the idea that it's because Raven is Yang's mother and therefore a real huntress with years of experience sounds way more plausible.


 * The encounter itself. Many people believe that it felt dream like and because of this they conclude that Yang was just dreaming that Raven is her mother but in reality she's dreaming that she sees Raven's face and thinks she's her mother. This is also supported by the idea that it's too convenient that Yang talked about her mother and now it turns out she appears? Where was she when those Beowolves were going to eat Yang and Ruby? Why didn't she show up in that moment?

The mother theory sounds better but the possibility that it's a twin sister is also there. And there is also a chance that she's neither of those but only one point supports that while the others support the mother and twin sister theories.
