Discover what a log-normal distribution is, its financial applications, and how to calculate it, including using Excel for practical financial analysis.

There are fundamental reasons why the normal distribution is a reasonable approximation in many development and manufacturing settings, but there are also practical reasons why data may not exactly ...

Measuring normal probability can be an aid in any type of situation in which you have uncertainty about the outcome. If currently using a distribution that does not fit the data, giving normal ...

The nonlinearity of the point pattern indicates a departure from normality. Since the point pattern is curved with slope increasing from left to right, a theoretical distribution that is skewed to the ...

Calculating probabilities on a normal distribution: Normal Distribution Calculator This web calculator allows users to specify the mean and standard deviation (SD) of the normal distribution, and ...

Von Mises distribution: A fundamental probability distribution in circular statistics, analogous to the normal distribution in linear settings.

A worst-case scenario includes values from the lower end of the probability distribution, the normal-case scenario includes mid-range values and the best-case scenario includes upper-range values.

You can use the RAND () function to establish probability and create a random variable with normal distribution.

In this article we review two historical approximations to the Poisson and binomial cumulative distribution functions (CDFs); that is, the Wilson—Hilferty and Camp—Paulson approximations. Both of ...
