Science - Physics
Italian term or phrase: Semidispersione
Si parla di un programma scolastico di fisica. Da un liceo scientifico.
Questo termine si trova nella sezione riguardante le misure.
Ecco il paragrafo:

LA MISURA
Gli strumenti di misura. L'incertezza nelle misure: errori sistematici e accidentali. Il valore medio e la semidispersione. [...]

Ho capito l'ambito e ho anche trovato la definizione di semidispersione, ma sto avendo seri problemi a trovare l'equivalente inglese.
Mille grazie a chi vorrà aiutarmi.

neutral  philgoddard: Maybe, but your Schott references are to optical dispersion, and this appears to be a statistical term.
