Use Goodness-of-Fit Test for Poisson to determine whether your data follow a Poisson distribution. Use this test when you count occurrences, such as the number of defects per unit.
For example, a quality engineer at a mobile phone manufacturer wants to know whether the data on the number of defects per phone follow a Poisson distribution.
To perform a goodness-of-fit test for the Poisson distribution, choose .
If you have continuous data, such as length, weight, or temperature, and want to determine whether the data follow a normal distribution, use Normality Test.
