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:
$$ f(x, μ, σ) = 1 / ( \sqrt{2 π} σ ) e^{-(x – μ)}^2 / 2 σ^2 $$
Where,
μ = mean
σ = variance
x = independent variable
