Normal Distribution: Definition, Formula, and Examples
WebThe Standard Normal Distribution Table. The standard normal distribution table provides the probability that a normally distributed random variable Z, with mean equal to 0 and variance equal to 1, is less than or equal to z. It does this for positive values of z only (i.e., z-values on the right-hand side of the mean).
