Častá chyba:
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.
