## distribution English Thesaurus

the distribution of charity

## gamma distribution British & World English

A continuous statistical distribution of two parameters α and β of which the chi-squared and exponential distributions are special cases, given by f(x) = βα x α−1 e −βx/Γ(α), for x, α, β all positive, where Γ is the gamma function.

## mass distribution British & World English

The distribution of goods in bulk.

## distribution board British & World English

A panel carrying the fuses, terminals, and other components of a number of subsidiary electric circuits

## geometric distribution British & World English

A frequency distribution giving the number of trials required to obtain a single successful outcome.

## Maxwell's distribution British & World English

The distribution of molecular velocities predicted by Maxwell's law, the number with a velocity between v and v + dv being proportional to exp (−mv 2 /kT)v 2dv (where m is the mass of a molecule, k is Boltzmann's constant, and T is the absolute temperature).

## random distribution British & World English

A distribution that is random or haphazard; (Statistics) a probability distribution, especially the Poisson distribution.

## binomial distribution British & World English

A frequency distribution of the possible number of successful outcomes in a given number of trials in each of which there is the same probability of success

## frequency distribution British & World English

A mathematical function showing the number of instances in which a variable takes each of its possible values

## Gaussian distribution British & World English

Another term for normal distribution.

## normal distribution British & World English

A function that represents the distribution of many random variables as a symmetrical bell-shaped graph

## Poisson distribution British & World English

A discrete frequency distribution which gives the probability of a number of independent events occurring in a fixed time

## complementary distribution British & World English

The occurrence of phenomena such as speech sounds in mutually exclusive contexts

## probability distribution British & World English

A function of a discrete variable whose integral over any interval is the probability that the variate specified by it will lie within that interval

## cumulative distribution function British & World English

A function whose value is the probability that a corresponding continuous random variable has a value less than or equal to the argument of the function

## Maxwell–Boltzmann distribution British & World English

A formula describing the statistical distribution of particles in a system among different energy levels. The number of particles in a given energy level is proportional to exp (−EkT), where E is the energy of the level, k is Boltzmann’s constant, and T is the absolute temperature

## maldistribution British & World English

Uneven, inefficient, or unfair distribution of something

## Student's t-test British & World English

A test for statistical significance that uses tables of a statistical distribution called Student’s t-distribution, which is that of a fraction (t) whose numerator is drawn from a normal distribution with a mean of zero, and whose denominator is the root mean square of k terms drawn from the same normal distribution (where k is the number of degrees of freedom)

## Student’s t-distribution in Student's t-test British & World English

A test for statistical significance that uses tables of a statistical distribution called Student’s t-distribution, which is that of a fraction (t) whose numerator is drawn from a normal distribution with a mean of zero, and whose denominator is the root mean square of k terms drawn from the same normal distribution (where k is the number of degrees of freedom)
