Probability distribution definition and tables. In probability and statistics distribution is a characteristic of a random variable, describes the probability of the random variable in each value. Each distribution has a certain probability density func

uniform distribution, in statistics, distribution function in which every possible result is equally likely; that is, the probability of each occurring is the same. As one of the simplest possible distributions, the uniform distribution is sometimes used as the null hypothesis, or initial hypothesis...
15.9% of all people score 115 points or more; a random person has a 50% (or 0.50) probability of scoring 100 points or lower.In statistics, the normal distribution plays 2 important roles:a frequency distribution (values over observations): for example, IQ scores are roughly normally distribu...
In 2023, Instagram influencers with 1,000 to 10,000 followers accounted for 76.86 percent of influencer accounts worldwide.

Half of the population is less than the mean and half is greater than the mean. The Empirical Rule allows you to determine the proportion of values that fall within certain distances from the mean. More on this below! While the normal distribution is essential in statistics, it is just one...
In statistics, a Poisson distribution is a discreteprobability distributionthat tells how many times an event is likely to occur over a specified period. It is a count distribution, the parameter of which is lambda (λ); the mean number of events in the specific interval. ...
LOGNORM.DIST(x,μ, σ, FALSE) = NORM.DIST(LN(x),μ, σ, FALSE)/x LOGNORM.INV(p,μ, σ) = EXP(NORM.INV(p,μ, σ)) These functions are not available in versions of Excel prior to Excel 2010. Instead, these versions of Excel useLOGNORMDIST(x,μ, σ), which is equivalent ...
David D. Hanagal, in Handbook of Statistics, 2017 8 Baseline Distributions 8.1 Generalized Log-Logistic Distribution The log-logistic distribution is very useful in a wide variety of applications, especially in the analysis of survival data (Bennett, 1983; Cox and Snell, 1989; O’Quigley and Str...
