Normal distribution with mean 0

WebA normal distribution is a statistical phenomenon representing a symmetric bell-shaped curve. Most values are located near the mean; also, only a few appear at the left and right tails. It follows the empirical rule or the 68-95-99.7 rule. Here, the mean, median, and mode are equal; the mean and standard deviation of the function are 0 and 1 ... WebReturns the normal distribution for the specified mean and standard deviation. This function has a very wide range of applications in statistics, including hypothesis testing. Syntax. NORM.DIST(x,mean,standard_dev,cumulative) The NORM.DIST function syntax has the following arguments: X Required. The value for which you want the distribution.

WebA z-score of a standard normal distribution is a standard score that indicates how many standard deviations are away from the mean an individual value (x) lies: When z-score is positive, the x-value is greater than the mean. When z-score is negative, the x-value is less than the mean. When z-score is equal to 0, the x-value is equal to the mean.
