InvNorm Calculator

Write down the values of probability, variance, and standard deviation in their designated fields to calculate confidence interval and inverse normal probability distribution through this calculator.

The online calculator invnorm can help you calculate the normality and standard probability distribution of your data set. It also shows graphs for degree of belief, left-handed, right-handed, and two-tailed based on the concept of probability (i.e., standard deviation).

What is inverse default distribution?

In fact, the normal distribution is a variable used to extract x values ​​from given probabilities. It is too long to distribute.

Formula

The Invnorm components makes use of the following parameters:

  • chance (required parameter): chance corresponding to a regular distribution.
  • Mean (required parameter): mathematics suggest of the distribution.
  • General deviation (required parameter): trendy 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,

m = mean

s = variance

x = random variable

How does the Invnorm calculator work?

The logarithm inverse distribution calculator helps you find the inverse probability distribution using the following formula:

Input:

  • First, standard substitutionof the mean of the behavior.
  • Click the Calculate button. .

Result:

  • The inverse standard deviation calculator displays left, right, end, and standard deviation values ​​on a graph.
