Weighted Rank (WR) = (v / (v + m)) * S + (m / (v + m)) * C

S = Average score for the Anime (mean).

v = Number of votes for the Anime = (Number of people scoring the Anime).

m = Minimum votes/scores required to get a calculated score (currently 50 scores required).

C = The mean score across the entire Anime DB.

Taken from official MAL description. The formula is the same for everything.
