Using Distribution Analysis

Use the Quality application client to view and interact with histograms, box plots, Pearson distribution types, and basic statistics. Quality provides the following single sample statistical confidence tests:

• A t-test, to test the mean of the current population versus a target mean supplied by you.

• A chi-square test, to test the standard deviation of the current population versus a target standard deviation that you supply.

This section discusses how to:

• Use histogram statistics.

• Use test statistics.
