A roving motion; course without definite direction; want of direction, rule, or method; hazard; chance; -- commonly used in the phrase at random, that is, without a settled point of direction; at hazard.
Going at random or by chance; done or made at hazard, or without settled direction, aim, or purpose; hazarded without previous calculation; left to chance; haphazard; as, a random guess.
of, pertaining to, or resulting from a process of selection from a starting set of items, in which the probability of selecting any one object in the starting set is equal to the probability of selecting any other.
Which cannot be predicted with certainty from the past.
Selecting a sample so each item in the population has an equal chance of being selected; lack of predictability; without pattern.
A number chosen without definite aim, reason, or pattern.
Refers to events that are, in principle, unpredictable. See also "chance".
A type of sample, selected in a way that gives each member of the population an equal chance of being included in the sample.
Lack of predictability, without any systematic pattern.
Arrived at by chance without discrimination.
Having no particular pattern or order.
Assignment of participants to different treatments, interventions, or conditions according to chance rather than systematically (e.g., as dictated by the standard or usual response to their condition, history, or prognosis, or according to demographic characteristics). Random assignment of participants to conditions is an essential element of experimental research because it makes more likely the probability that differences observed between subject groups are the result of the experimental intervention.
Random relationships cannot be predicted. EX: In assigning patients to treatments in a random fashion, there should be no knowledge of any characteristic of the treatment, the patient, or any previous patient or treatment that permits guessing the assignment with anything more than chance probability. [See also bias, independent sampling
without any pattern or organization Computer functions often seem to be given random names. randomly (adv), randomness (n)
Lacking any definite plan or prearranged order; haphazard; having a value which cannot be determined but only described in terms of probability; chosen without regard to any characteristics of the individual members of the population so that each has an equal chance of being selected; lacking a definite plan, purpose or pattern; relating to, or having, or being statistical elements or events with an ungoverned or unpredictable outcome, but with a definite probability of occurrence.
5rAndEm/ adj. occurring or done without definite aim, reason or pattern
without order or apparent reason. Sometimes the police patrol van comes past every hour so you can predict when they will be around, but in other places they seem to patrol at random, and so you never know if the cops will show up while you are busy. If you chose a number at random between 0 and 1, the chance is 1 in 4 that it will be less than 0.25.
Selection of a sample so that each member of the universe has an equal chance of being chosen.
stone pattern where joints are web-like.
An unpredictable pattern. Pesudorandom numbers are used extensively in cryptography.
Haphazard; not determined by any known pattern.
no particular means of choosing, by chance
Affected by chance.
n. –ness adj. When events or players’ actions in a game are very unpredictable. Often players will have little, if any, control over the elements that control their performance in the game. (See also luck)
seemingly haphazard, illogical, unreasonable or irrational occurrence or idea. See mad
Having no predictable pattern. For example, sales data may vary randomly about some forecast value with no specific pattern and no attendant ability to obtain a more accurate sales estimate than the forecast value.
Without any pattern or preference.
The process by which an outcome is determined solely by chance, for example, by a coin flip. See the entire definition of Random
Eluding precise prediction, completely irregular.
No such thing; or, virtually impossible to predict.
With no specific pattern. [Shooting in random directions is a sure way not to hit your target.
chosen with no specific pattern, haphazard.
A way to choose a sample that represents all the people we want to reach (in political polling, that's usually likely voters). A sample is random if each member of the population has an equal chance of being represented.
Governed by a formal chance process in which the occurrence of previous events is of no value in predicting future events. The probability of assignment of, for example, a given subject to a specified treatment group is fixed and constant (typically 0.50) but the subject's actual assignment cannot be known until it occurs.
Occuring without a regular or predictable pattern
Not planned. Not uniform. Unpredictable.
