When analyzing data for quality, you need to
choose a control chart on the basis of the type
of data you have collected and the sample size
you have drawn. We have created two versions
of Chart Guides to help you select the most
appropriate chart for your situation: one for
attribute data, and the other for variable data.
Both contain a decision matrix and sample charts
which will guide you to selecting the best analysis
strategy for your data.
