variance of the standard normal distribution

What is the of the ?
The variance of Standard Normal Distribution represented by ##sigma^2## is equal to unity. ##sigma^2=1##
A Standard Normal Distribution is a normal distribution with zero mean (mu=0) and unit variance (sigma^2=1), given by the probability density function and distribution function
##P(x) = 1/(sqrt(2pi))e^(-x^2/2)## ##D(x) = 1/2[erf(x/(sqrt(2)))+1##
over the domain x in ##(-infty,infty)##
It has mean, variance, skewness, and kurtosis excess given by
##mu = 0##
##sigma^2 = 1##
##gamma_1 = 0##
##gamma_2 = 0##
