This example uses the Socket Thickness.jmp sample data table, which includes measurements for the thickness of sockets. There has been an increase in the number of defects during production and you want to investigate why this is occurring. Use Control Chart Builder to investigate the variability in the data and the control of the process.
1.
Open the Socket Thickness.jmp sample data table from the Quality Control folder.
2.
Select Analyze > Quality and Process > Control Chart Builder.
3.
Drag Thickness to the Y zone.
4.
Drag Hour to the Subgroup zone (at bottom).
