Standard normal distribution occurs when a normal random variable has a mean equal to zero and a standard deviation equal to one. Learn more about standard normal distribution with solved problems at BYJU'S.
The meaning of STANDARD ERROR is the standard deviation of the probability function or probability density function of a random variable and especially of a statistic; specifically : the standard error of the mean of a sample from a population with a nor
The Normal Distribution, also called the Gaussian distribution, as we know is the most significant continuous probability distribution in statistics and probability. The Normal Distribution is defined by the probability density function for a continuous random variable in a system. It is used to approx...
