A(z) is the integral of the standardized normal distribution from −∞to z (in other words, the area under the curve to the left of z). It gives the probability of a normal random variable not being more than z standard deviations above its mean. Values of z of particular importance: .

A vertical line drawn through a normal distribution at a z-score location divides the distri- bution into two sections. Column B identifies the proportion in the larger section, called the body. Column C identifies the proportion in the smaller section, called the tail. A score of 60, where the mean score of the sample data values is 40. Z=2. A score that is 30 points below the mean. z=-3. A score of 80, where the mean score of the sample data values is 30. Z=5. A score of 20, where the mean score of the sample data values is 50. Z=-3. IQ scores have a mean of 100 and a standard deviation of 16. A Z-Score chart, often called a Z-Table, is used to find the area under a normal curve, or bell curve, for a binomial distribution. The Z score itself is a statistical measurement of the number of standard variations from the mean of a normal distribution.

Example: Actual length 96.1 cm Median 90.4 cm Standard deviation 3.3 Z score = 5.7/3.3 = +1.73 Comparison of growth charts. Percentile graphs have a narrower range, because the 97th centile corresponds approximately to a Z score +2. A Z-score of +3 or -3 is more likely to be definitely abnormal.
