= NORM.S.DIST(z, cumulative)


  • Z    – The value for which you want the distribution.
  • Cumulative – Cumulative is a logical value either TRUE or FALSE which determines the form of the function. If cumulative is TRUE, the function returns the cumulative distribution function; and when FALSE, it returns the probability mass function.

How to use the NORM.S.DIST Function in Excel?

To find the standard normal distribution of the given numbers, enter the z value in column A, and Cummulative at column B and enter the following formula in Column C,

Formula: = NORM.S.DIST(A1,TRUE)

Here, A1 refers to the cell name or the cell address.

When entered,  the function gives you the standard normal distribution of the given numbers. Follow the same to other cells and you will get the standard normal distribution for the rest of the numbers.
