Bernoulli trial
Bernoulli trialn. Statistics An experiment having only two possible outcomes, usually denoted success and failure, with the properties that the probability of occurrence of each outcome is the same in each trial and the occurrence of one excludes the occurrence of the other in any given trial.
[After Jakob Bernoulli.]Bernoulli trial n (Statistics) statistics one of a sequence of independent experiments each of which has the same probability of success, such as successive throws of a die, the outcome of which is described by a binomial distribution. See also binomial experiment, geometric distribution [named after Jacques Bernoulli]EncyclopediaSeeBernoulli trialsBernoulli trial
Ber·noul·li tri·al (bĕr-nū'lē), A single random event for which there are two and only two possible outcomes that are mutually exclusive and have a priori fixed (and complementary) probabilities of resulting. The trial is the realization of this process. Conventionally one outcome is termed a success and is assigned the score 1, the other is a failure and has the score 0. Thus the outcome might be 0 (no heads, one tail) or 1 (1 head, no tails).Bernoulli Trial
Bernoulli TrialA test in which there are precisely two random outcomes: success and failure. For example, if one is testing whether flipping a coin will result in heads, the two outcomes are yes (success) and no (failure). See also: Bernoulli's Law. |
