How to perform a uniform distribution in Excel - Quora

Answer (1 of 2): You can use the RAND() function. It will generate random numbers in the interval 0 - 1 (so an uniform distribution). All you need is to switch this uniform distribution in the interval that you desire. If you need an uniform distribution between a and b (so centered around (a+b)...

Uniform distribution. Let X sim U(a, b), this is, a random variable with uniform distribution in the interval (a, b), with a, b in mathbb{R}, a < b:. The probability density function (PDF) of x is f(x) = frac{1}{b - a} if x in (a, b) and 0 otherwise.; The cumulative distribution function (CDF) is F(x) = P(X leq x) = frac{x-a}{b-a}.; The quantile function is Q(p) = F^{-1}(p).

Uniform Distribution | Real Statistics Using Excel

UNIFORM_INV(p, α, β) = x such that UNIFORM_DIST(x, α, β, TRUE) = p. Thus UNIFORM_INV is the inverse of the cumulative uniform distribution. Observation: A continuous uniform distribution in the interval (0, 1) can be expressed as a beta distribution with parameters α = 1 and β = 1. Examples
