Normal Distribution and its Significance by Roshmita Dey

normal distribution  In a standard normal distribution, the mean by itself is equal to 0, and the standard deviation The Probability Density Function for a Normal X ∼ N is: f X = 1 σ 2 π e − 2 2 σ 2 Notice the x in the exponent of the PDF

A normal distribution in a variate X with mean mu and variance sigma^2 is a statistic distribution with probability density function The Probability Density Function for a Normal X ∼ N is: f X = 1 σ 2 π e − 2 2 σ 2 Notice the x in the exponent of the PDF

The standard normal distribution is a special normal distribution with a µ = 0 and σ = 1 We can use the Z-score to standardize any normal random variable, The Standard Normal Distribution The standard normal distribution is a special case of the normal distribution For the standard normal distribution the value
