# NORMSDIST

The NORMSDIST function calculates the standard normal cumulative distribution function for a specified value in Excel. This function is commonly used in statistical analysis to determine the probability that a value falls below a certain point in a standard normal distribution.

## Syntax

=NORMSDIST(`Z`

)

`Z` | The value for which you want to calculate the standard normal cumulative distribution function. |

## About NORMSDIST

When dealing with statistical analysis and the need to ascertain the likelihood of a value occurring within a standard normal distribution, NORMSDIST in Excel comes to your aid. It serves as a valuable tool for determining the cumulative probability of a value falling below a specified point in a standard normal curve, facilitating the interpretation of statistical data with ease and precision. This function is particularly helpful in scenarios requiring the assessment of probabilities in various fields, including finance, research, and quality control. By inputting the desired value into NORMSDIST, you can swiftly obtain the corresponding cumulative probability, aiding in informed decision-making and trend analysis.

## Examples

If you want to find the probability that a standard normal random variable is less than 1.5, you would use the formula: =NORMSDIST(1.5). This will give you the cumulative probability that the random variable is less than 1.5 in a standard normal distribution.

## Notes

The NORMSDIST function assumes a standard normal distribution with a mean of 0 and a standard deviation of 1. Make sure to enter the correct value for 'Z' corresponding to the point you are considering within the standard normal curve.

## Questions

**How does the NORMSDIST function work?**

The NORMSDIST function calculates the area under the standard normal curve to the left of a specified value. This area represents the cumulative probability that a random variable from a standard normal distribution is less than or equal to the given value.

**What range of values can be inputted into the NORMSDIST function?**

You can input any real number into the NORMSDIST function as the 'Z' value. The function will return the cumulative probability for that specific value within the standard normal distribution.
