# PHI

Formulas / PHI
Calculate the density function for a standard normal distribution.
`=PHI(X)`
• X - the number for which the standard normal distribution is calculated

## Examples

• `=PHI(0.5)`

The PHI function can be used to calculate the probability of a normal distribution with a given mean and standard deviation. For example, if you wanted to calculate the probability of a normal distribution with a mean of 0 and a standard deviation of 1, you could use the above formula. This would return the value of the density function for a standard normal distribution.

## Summary

The PHI function is a mathematical tool used to calculate the probability of a given value for a standard normal distribution. It is used to determine the likelihood of a given value occurring in a normal distribution.

• The PHI function takes a numeric argument to calculate the value of the density function for a standard normal distribution.
• The numeric argument is required and is the number to calculate the density of the standard normal distribution on.

What is the PHI function?
