An online invnorm calculator helps you to compute the inverse normal probability distribution and confidence interval for the given values. It also displays a graph for confidence level, left, right and two tails on the basis of probability, mean, standard deviation.

In statistics, the inverse normal distribution is an inverse working method of finding the value of x from a known probability. This is an informal term and does not involve any specific probability distribution.

The Invnorm formula uses the following parameters:

- Probability (required parameter): Probability corresponding to a normal distribution.
- Mean (required parameter): Arithmetic mean of the distribution.
- Standard deviation (required parameter): Standard deviation of distribution.

\(f\left(x, μ, σ\right) = \dfrac{1}{ σ\sqrt{2 π}}\int_{- \inf}^{x} e\left(\dfrac{-\left(t-μ\right)^{2}}{2σ^{2}}\right)dt\)

Where,

μ = mean

σ = variance

x = independent variable

An online inverse normal distribution calculator helps you to find inverse probability distribution by following steps:

- First, substitute the values for Probability, Mean, and Standard Deviation.
- Hit the calculate button.

- The inverse norm calculator displays the values for left, right, two tails and standard deviation with graph.
