WebA normal distribution curve is plotted along a horizontal axis labeled, Mean, which ranges from negative 3 to 3 in increments of 1 The curve rises from the horizontal axis at negative 3 with increasing steepness to its peak at 0, before falling with decreasing steepness through 3, then appearing to plateau along the horizontal axis.

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.
