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. WebThis is the "bell-shaped" curve of the Standard Normal Distribution.
