Enter the chosen values of x1 and, if required, x2 then press Calculate to calculate the probability that a value chosen at random from the distribution is greater than or less than x1 or x2, or lies between x1
Normal Distribution CalculatorEnter the raw score, mean, and standard deviation to find the probability of getting a number above or below that score using the normal distribution calculator below. Mean (μ): Standard Deviation (σ): Raw Score (x): ...
where erf-1 is the inverse error function,μ is the mean and σ is the standard deviation. The computation of normal quantiles is not straightforward which is why p value to z score tables were precomputed and distributed in the past. Nowadays a normal distribution probability calculator will ...

The standard normal distribution is a special case of the normal distribution. It contains the following parameters: a mean of 0 and a standard deviation of 1.When X follows a normal distribution with mean (μ) and standard deviation (σ), the standardized value Z = (x-μ)/σ follows ...
Decide on the calculator mode, based on what you need to calculate: this lognormal distribution calculator has as many as six modes! Select a common measures option to estimate, e.g., the mean of lognormal distribution. Enter the parameters for the lognormal distribution. If needed, fill in...
