What does the inverse function of the normal distribution mean
Formula: = NORMINV(Probability Value, Arithmetic Mean, Standard Deviation Value)

NORMSINV( X ) returns the interval points of a standard normal distribution.

NORMINV( X, MEAN, STARDARD VARIANCE) returns the interval points of a non-standard normal distribution.

Normal distribution :

Normal distribution (Normal distribution), also known as the Gaussian distribution (Gaussian distribution), is a very important probability distribution in the fields of mathematics, physics and engineering, and has a significant impact in many aspects of statistics. If a random variable X obeys a Gaussian distribution with mathematical expectation μ and variance σ^2, denoted N(μ, σ^2). Its probability density function is normal with expectation μ determining its location and its standard deviation σ determining the magnitude of the distribution. It is also often referred to as a bell-shaped curve because of its bell-shaped curve. The standard normal distribution we usually refer to is the one with μ = 0 and σ = 1.
