Normal distribution mean standard deviation
WebFor example, if the mean of a normal distribution is five and the standard deviation is two, the value 11 is three standard deviations above (or to the right of) the mean. The calculation is as follows: x = μ + (z)(σ) = 5 + (3)(2) = 11. The z-score is three. The mean for the standard normal distribution is zero, and the standard deviation is one. WebThe standard normal distribution is one of the forms of the normal distribution. It occurs when a normal random variable has a mean equal to zero and a standard deviation …
