PHI function

The PHI function returns the value of the density function for a normal distribution with mean 0 and standard deviation 1, calculated with the formula .

Parts of a PHI function

PHI(x)

Parts	Description
`x`	The input to the standard normal distribution function.

Sample formula

PHI(0.25)

Notes

This is a special case of the NORMDIST function, where mean is 0, standard deviation is 1, and 'cumulative' is false.

Examples

	A	B
1	Formula	Result
2	=PHI(0.5)	0.3520653268
3	=PHI(1)	0.2419707245
4	=PHI(1.5)	0.1295175957

Related functions

STDEV: The STDEV function calculates the standard deviation based on a sample.
NORMDIST: The NORMDIST function returns the value of the normal distribution function (or normal cumulative distribution function) for a specified value, mean, and standard deviation.
