átlagtól

átlagtól is a Hungarian postpositional phrase meaning "from the mean" or "away from the average." It is used to express distance or deviation relative to the statistical mean of a data set. In statistical language, it helps describe how far a value lies from the average rather than describing the value itself. The term appears in both mathematical and everyday contexts when discussing departures from typical or expected values.

Etymology and grammar: the form is built from the noun átlag (mean, average) plus the postpositional suffix -tól, which marks movement from a reference point. The resulting átlagtól functions as a complement indicating distance from the mean and can be used with verbs and phrases that describe deviation or comparison. In practice, it often occurs in constructions with verbs like tér el (deviate) or with phrases such as az átlagtól vett/ számított eltérés.

Usage in statistics and language: átlagtól is commonly used to introduce measurements of deviation, such as "az érték az átlagtól 3 egységgel tér el" (the value deviates from the mean by 3 units). It can also appear in discussions of data dispersion, where researchers refer to "az átlagtól számított eltérések" or "az átlagtól való eltérés." While primarily a statistical term, it may occur in general prose to describe how far an observation is from what is typical or expected.
