distributions
noun(dis-tri-bu-tion)the act or process of distributing
distributions
noun(dis-tri-bu-tion)the act or process of apportioning by a court the personal property of an intestate
distributions
noun(dis-tri-bu-tion)the position, arrangement, or frequency of occurrence (as of the members of a group) over an area or throughout a space or unit of time
distributions
noun(dis-tri-bu-tion)a probability function each of whose values gives the probability that an outcome with constant probability of occurrence in a statistical experiment will occur a given number of times in a succession of repetitions of the experiment
distributions
noun(dis-tri-bu-tion)a probability density function that gives the distribution of the sum of the squares of a number of independent random variables each with a normal distribution with zero mean and unit variance, that has the property that the sum of two or more random variables with such a distribution also has one, and that is widely used in testing statistical hypotheses especially about the theoretical and observed values of a quantity and about population variances and standard deviations
distributions
noun(dis-tri-bu-tion)a probability density function that is used especially in analysis of variance and is a function of the ratio of two independent random variables each of which has a chi-square distribution and is divided by its number of degrees of freedom
distributions
noun(dis-tri-bu-tion)an arrangement of statistical data that exhibits the frequency of the occurrence of the values of a variable
distributions
noun(dis-tri-bu-tion)normal distribution
distributions
noun(dis-tri-bu-tion)a probability function f(x) that gives the probability of obtaining exactly x elements of one kind and n - x elements of another if n elements are chosen at random without replacement from a finite population containing N elements of which M are of the first kind and N - M are of the second kind and that has the form ...
distributions
noun(dis-tri-bu-tion)a probability density function that approximates the distribution of many random variables (such as the proportion of outcomes of a particular kind in a large number of independent repetitions of an experiment in which the probabilities remain constant from trial to trial) and that has the form ... where μ is the mean and σ is the standard deviation
distributions
noun(dis-tri-bu-tion)a probability density function that is often used as a mathematical model of the number of outcomes obtained in a suitable interval of time and space, that has its mean equal to its variance, that is used as an approximation to the binomial distribution, and that has the form ... where μ is the mean and x takes on nonnegative integral values
