Sagot :
A standard normal distribution's characteristics are its mean is equal to 0 and the standard deviation is 1. Thus, the variance is equal to 1.
What is a standard normal distribution?
A normal distribution that has a mean value of 0 and a standard deviation or a variance of 1 is said to be a standard normal distribution.
I.e., μ = 0 and σ² = 1
This is also called z-distribution.
Calculation:
A standard normal distribution has μ = 0 and σ² = 1.
So, the probability of a normal random variable is calculated by using a z-score.
The z-score value is calculated by the formula
z = (X - μ)/σ
Where mean (μ) and standard deviation (σ) for the variable X
By using the standard normal distribution tables with the z-score and probabilities, the required values are calculated.
So, we can conclude that the major characteristics of a standard normal distribution are mean = 0 and variance = 1.
