Scatter Plot

In the Scatter Plot the values are grouped by part number, e.g. all of the readings for part number 1 are plotted together in the first group.  The Scatter Plot for the AIAG data set is shown below.

The form of the plot is basically the same as a Normalised Individuals Chart: the main difference being that the actual values are plotted, rather than the normalised values. 

The Scatter Plot is useful for assessing:

       consistency between operators

       existence of outliers

       operator-part interactions
