independent random variables
vatandehâ-ye kâture-ye nâvâbasté
Fr.: variables aléatoires indépendantes
Statistics: Two random variables X and Y if and only if the value of X has no influence on the value of Y and vice versa.
Fr.: aléatoire, au hasard
1) General: Made or occurring without a definite pattern, plan, or system;
haphazard arrangement as if due to pure chance.
M.E. raundon, random "impetuosity, speed," from O.Fr. randon "rush, disorder, impetuosity," from randir "to run fast."
Kâturé originally "dazzled, confused," variants katré "disorderly, ragged, tattered, babble, meaningless or incoherent speech," katreyi "disorderly, at random;" maybe from kat- "to fall;" → case.
random access memory (RAM)
barm bâ dastrasi-ye kâtruré
Fr.: mémoire à accès aléatoire
In computer technique, a configuration of memory cells that hold data for processing by a central processing unit (CPU). The term random derives from the fact that the CPU can retrieve data from any individual location, or address, within RAM.
Fr.: erreur fortuite
The fluctuating part of the overall error that varies from measurement to measurement. Normally, the random error is defined as the deviation of the total error from its mean value; opposite of → systematic error.
âzmâyešhâ-ye kâturé (#)
Fr.: expériences aléatoires
Statistics: Experiments in which results will not be essentially the same even though conditions may be nearly identical.
→ random; → experiment.
Fr.: bruit aléatoire
Unpredictable noise comprising large numbers of frequent, transient impulses occurring at statistically random time intervals. Thermal noise is a form of random noise.
Fr.: échantillon aléatoire
A sample selected at random from a population.
Fr.: structure aléatoire
Crystalline arrangement in which equivalent positions are not necessarily occupied by atoms of a single kind.
random thermal motion
jonbeš-e garmâyi-ye kâturé
Fr.: mouvement thermique aléatoire
The agitated motion of molecular, atomic, or → subatomic particles in all possible directions at any temperature, except at → absolute zero, where → thermal motion would cease.
Fr.: variable aléatoire
A quantity that takes different real values as a result of the → outcomes of a → random event or experiment involving specified probabilities.
Fr.: marche aléatoire, ~ au hasard
The trajectory consisting of a series of successive moves in which the direction and size of each move is randomly determined.
Arrangement of data in such a way as to simulate chance occurrence.
Verbal noun of → randomize.
Fr.: répartir au hasard
To arrange or select in a random manner in order to reduce bias and interference caused by irrelevant variables.
Verbal form of → random.
The property of being random.
State, condition noun of → random.
