Thus, we are able to calculate the probability for any range of values for a normal distribution using a standard distribution table. It will first show you how to interpret a Standard Normal Distribution Table. Using the information from the example, you know that. Calculate the Z value using the following formula for Z. Popular Courses. If the Z score of x is two, then the value of x is two standard deviations above the mean. Work Problems. Enter mean, standard deviation and cutoff points in order to find the area under normal curve.

How to do Normal Distributions Calculations

Using Standard Normal Distribution Tables. Arithmetic Sequences. It is the sum of individual scores divided by the number of individuals. Returning to the example of apparel shipments, you can look up the Z score of 2. Thus, we can do the following to calculate negative z-values: Enter a value in three of the four text boxes. Solution 3. If you don't see the answer you need, try the Statistics Glossary or check out Stat Trek's tutorial on the normal distribution.
