General: A standard, model, or pattern regarded as typical. Math.:
1) The magnitude of a vector expressed as the square root of the sum of
the squares of the absolute values of the components of the vector.
2) The value that has the highest frequency within a statistical range.

From Fr. norme, from O.Fr., from L. norma "carpenter's square, rule,
pattern," of unknown origin.

Hanjâr "a straight road; way, rule, law; habit, custom; conduct;
a mason's rule, a plumb-line, a level;" Mid.Pers. hanjâr "right, correct;"
from Proto-Iranian *ham-cara-, *han-cara- prefixed *cara-
"to move, walk" (cf. Av. car- "to move, go, walk," carāni "I would go,"
carāt "he would go;" Mod.Pers. caridan "to graze," gozârdan
"to explain," gozâreš "explanation"); cf. Skt. samcara-
"passage, way, road, path; going about, moving,"
from prefix sam- + cara- "moving, going, walking;" Gk. pelomai
"to move;" L. colere "to till, cultivate, inhabit."

Norma

گونیا

Guniyâ (#)

Fr.: Règle

The Carpenter's Square. A small and inconspicuous southern constellation
which lies between → Scorpius and
→ Centaurus. Its brightest star
is only of magnitude 4.0. Abbreviation: Nor; genitive: Normae

Initially Norma et Regula, L. translation of
l'Équerre et la Règle "the Set Square and the Ruler,"
as named by Abbé Nicolas Louis de Lacaille (1713-1762).

Guniyâ "carpenter's square," probably related to
konj "angle, corner, confined place" (variants xong "corner, angle,"
Tabari kânj, Kurd. kunj, Hamadâni kom) and
zânu "knee" (Av. žnu-),
Skt. kona- "angle, corner," Gk. gonia "angle,",
gony "knee," L. genu "knee," cuneus
"a wedge," Albanian (Gheg dialect) kân "angle, corner," Albanian (Toks)
kënd "angle, corner;" PIE base PIE base *g(e)neu-.

normal

۱) هنجارور، هنجارمند؛ ۲) هنجار

1) hanjârvar, hanjârmand; 2) hanjâr;

Fr.: 1) normal; 2) normale

1) Conforming to the usual standard, type, custom; not abnormal; regular; natural.
2a) Math.: A perpendicular, particularly a line perpendicular to the tangent of a curve
or curved surface at the point of contact of the tangent with the curve or the curved surface.
See also → perpendicular;
→ vertical.
2b) Optics: A line drawn perpendicular to the surface of a reflecting or
refracting medium.

From L.L. normalis "standing at right angle, in conformity with rule,"
from L. normalis "made according to a carpenter's square," from norma
"rule, pattern," literally "carpenter's square."

Hanjârvar, hanjârmand, adjectives of hanjâr,
→ norm.

A theoretical frequency distribution for a set of variable data,
usually represented by a bell-shaped curve with a mean at the center
of the curve and tail widths proportional to the standard deviation of
the data about the mean. Same as → Gaussian distribution.

1) A mathematical technique for adjusting a series of values (typically representing a set of
measurements) according to some transformation function in order to make
them comparable with some specific point of reference.
2) Process of introducing a numerical factor into an equation so that the area under
the corresponding graph (if finite) shall be made equal to unity.
3) To change in scale so that the sum of squares or the integral of squares of the transformed
quantity is zero.
