The standard normal distribution’s standard deviation is always 1. This means that one standard deviation of the raw score, no matter what the raw value is, always converts into 1 z score unit. The standard normal distribution always features the same shape of the raw score distribution. So...
Standard normal distribution is a special case of normal distribution with mean 0 and variance 1. Conversion of normal distribution to standard normal distribution can be done as follows: {eq}z = \dfrac{{x - \mu }}{\sigma } {/eq...
values. In the case of the standard normal distribution, these values are known as thez-scores. This distribution has a mean(μ=0)and standard deviation(σ=1). Standard normal probabilities are obtained with the help of a...
