NORM.DIST Function (DAX)

How does the NORM.DIST function (DAX) work?

The NORM.DIST function (DAX) returns the normal distribution for the specified mean and standard deviation.

NORM.DIST Formula Syntax

NORM.DIST(
     X, Mean, Standard_dev, Cumulative
)

How do you use the NORM.DIST function?

This function will calculate the probability that variable x falls below or at a specified value. That is, it will calculate the normal probability density function or the cumulative normal distribution function for a given set of parameters.

Considerations when using the NORM.DIST function

The NORM.DIST uses the following arguments:

  1. X (required argument) – This is the value for which we wish to calculate the distribution.
  2. Mean (required argument) – The arithmetic mean of the distribution.
  3. Standard_dev (required argument) – The standard deviation of the distribution.
  4. Cumulative (required argument) – This is a logical value. It specifies the type of distribution to be used: TRUE (Cumulative Normal Distribution Function) or FALSE (Normal Probability Density Function).

We can use 1 for TRUE and 0 for FALSE when entering the formula.
