amount of difference between things

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

Vzorec užití: variance in [something]; variance between [things]
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.
Synonyma
difference (More general and common; does not suggest measurement as strongly as "variance".)
Antonyma
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.

Vzorec užití: the variance of [a variable]; variance in [data]
Častá chyba:
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.
Synonyma
dispersion (A broader technical term for spread; not always a specific numerical measure like variance.)
Antonyma
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.

Vzorec užití: [something] is at variance with [something]
Častá chyba:
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.
Synonyma
conflict (Stronger and more general; can suggest active fighting, while "variance" is often about mismatch or disagreement in facts, ideas, or statements.)
Antonyma
accord (Suggests agreement and harmony, the opposite of being in disagreement.)

official permission as an exception

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

Vzorec užití: a variance to [do something]; a variance from [a rule]
Častá chyba:
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.
Synonyma
exemption (Similar idea of being released from a rule, but "variance" is more specific to planning, zoning, and regulatory contexts.)
Antonyma
compliance (Following the rules fully instead of receiving special permission to break them.)
Kolokace
grant a variance |request a variance |apply for a variance |zoning variance |building code variance |variance from regulations
Témata
