SDC = 2 × |A∩B| / (|A| + |B|) |
SDC = 2 × |A∩B| / (|A| + |B|) |

where A, B and A∩B are to be understood as multisets, and that if an item, x, has multiplicity a in A and b in B, then it will have multiplicity min(a,b) in A∩B. |

The Sørensen–Dice coefficient is thus a ratio between 0.0 and 1.0 giving the "percent similarity" between the two populations. |
