# Normal CDF Calculator

Cumulative Distribution Function states that the probability of the real-valued random variable X, will always take a value less than or equal to X. It is used to specify the distribution of multivariate random variables. It is also referred as cumulative density function or shortly, CDF. Use our online Cumulative distribution function calculator for cumulative density function calculation. Normal CDF calculator works based on the standard deviation, percentile and mean value.

Probability Function f(x, μ, σ) = 1 / (√ (2 x Π) x a x e(-1 / 2 x ((b - c) / a)2) Lower cumulative distribution P(x, μ, σ) = -∞x f(x, μ, σ) dt Upper cumulative distribution Q(x, μ, σ) = x f(x, μ, σ) dt Where, a = Standard Deviation σ b = Percentile x c = Mean μ

Fast in computation of results, ease in using and reliability in the results are the notable features of this online Normal CDF calculator.
