In what follows, the uppercase Z Z Z stands for the test statistic (treated as a random variable), while the lowercase z z z will denote an actual value of Z Z Z, computed for a given sample drawn from N(μ,σ²). The z-score, also referred to as standard score, z-value, and normal score, among other things, is a dimensionless quantity that is used to indicate the signed, fractional, number of standard deviations by which an event is above the mean value being measured. Values above the mean have positive z-scores, while values below the mean have negative z-scores. Why has the letter Z become the symbol of war for Russia?". The Guardian. 2022-03-07 .

In earlier times, the English alphabets used by children terminated not with Z but with & or related typographic symbols. [7] In her 1859 novel Adam Bede, George Eliot refers to Z being followed by & when her character Jacob Storey says, "He thought it [Z] had only been put to finish off th' alphabet like; though ampusand would ha' done as well, for what he could see."

In some inscriptions, z represented a Vulgar Latin sound, likely an affricate, formed by the merging of the reflexes of Classical Latin / j/, /dj/ and /gj/: [ example needed] for example, zanuariu for ianuariu "January", ziaconus for diaconus "deacon", and oze for hodie "today". [5] Likewise, /di/ sometimes replaced / z/ in words like baptidiare for baptizare "to baptize". In modern Italian, z represents / ts/ or / dz/, whereas the reflexes of ianuarius and hodie are written with the letter g (representing /dʒ/ when before i and e): gennaio, oggi. In other languages, such as Spanish, further evolution of the sound occurred.

The Greek form of Z was a close copy of the Phoenician Zayin ( ), and the Greek inscriptional form remained in this shape throughout ancient times. The Greeks called it zeta, a new name made in imitation of eta (η) and theta (θ).

Z, or z, is the 26th and last letter of the Latin alphabet, as used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its usual names in English are zed ( / ˈ z ɛ d/) and zee ( / ˈ z iː/), with an occasional archaic variant izzard ( / ˈ ɪ z ər d/). [1] Name and pronunciation [ edit ] In earlier Greek of Athens and Northwest Greece, the letter seems to have represented / dz/; in Attic, from the 4th century BC onwards, it seems to have stood for /zd/ and / dz/ – there is no consensus concerning this issue. [4] In other dialects, such as Elean and Cretan, the symbol seems to have been used for sounds resembling the English voiced and voiceless th (IPA / ð/ and / θ/, respectively). In the common dialect ( koine) that succeeded the older dialects, ζ became / z/, as it remains in modern Greek.
