Disagreement, variance, and discrepancy all mean a lack of agreement. Disagreement is a conflict of opinion between people. Variance is a formal, numerical term for how much two figures differ. Discrepancy means two things that should match but do not. Not compared: variance's statistical meaning.

这三个词都表示“不一致”或“差异”，但侧重点不同：disagreement 侧重人与人之间意见不合甚至发生争执；variance 侧重两个数值或事物之间量的差异，语气较中性正式；discrepancy 侧重本应一致的事物之间出现的不符，常暗示需要查明原因。此处不比较其他义项，例如 variance 在统计学中还有专门的“方差”含义，这里不涉及。
