常见错误：
Learners often confuse "variance" with "variation." In everyday English, "variation" is more common for small changes over time or between things (e.g., "temperature variation"), while "variance" often sounds more technical or formal and refers to the degree of difference, sometimes in a measured or calculated way.
含义
amount of difference between things
搭配
variance in results
|variance between groups
|a wide variance
|considerable variance
|reduce variance
|price variance
近义词
difference (More general and common; does not suggest measurement as strongly as "variance".)
反义词
uniformity (Emphasizes everything being the same, with no noticeable difference.)
