SPC Chart Guides

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.
