Sostantivo B2 quantity

amount of difference between things

The amount of difference between things, or between something and what is usual or expected.

Schema d'uso: variance in [something]; variance between [things]
Errore comune:
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.
Sinonimi
difference (More general and common; does not suggest measurement as strongly as "variance".)
Contrari
uniformity (Emphasizes everything being the same, with no noticeable difference.)

statistical measure of spread

In statistics, a number that shows how much the values in a group of numbers are spread out around the average.

Schema d'uso: the variance of [a variable]; variance in [data]
Errore comune:
Learners often confuse "variance" with "standard deviation." Variance is the average of the squared differences from the mean, while standard deviation is the square root of the variance and has the same units as the original data.
Sinonimi
dispersion (A broader technical term for spread; not always a specific numerical measure like variance.)
Contrari
constancy (If variance is zero, values do not change; they are constant.)

state of disagreement or conflict

A state where two things do not agree or do not match each other.

Schema d'uso: [something] is at variance with [something]
Errore comune:
Learners may say *"in variance with"* instead of the more natural fixed phrase "at variance with" when they mean "in disagreement with." "In variance" is rare; use "at variance with" in most formal contexts.
Sinonimi
conflict (Stronger and more general; can suggest active fighting, while "variance" is often about mismatch or disagreement in facts, ideas, or statements.)
Contrari
accord (Suggests agreement and harmony, the opposite of being in disagreement.)
Collocazioni

official permission as an exception

An official document or decision that lets a person do something that the normal rules do not allow.

Schema d'uso: a variance to [do something]; a variance from [a rule]
Errore comune:
Learners sometimes think this meaning of "variance" is just another word for "difference." In legal and planning contexts, "a variance" is a specific permission to break or change a rule, not just a general difference.
Sinonimi
exemption (Similar idea of being released from a rule, but "variance" is more specific to planning, zoning, and regulatory contexts.)
Contrari
compliance (Following the rules fully instead of receiving special permission to break them.)
Collocazioni
