Identify all the statements below regarding control charts that are True: Attribute control charts are less sensitive than variable control charts to changes in your process Unlike other control charts, pre-control charts are not statistically based. Control charts are robust enough that data can be re-arranged on the X-axis and will still detect when a process is out of statistical control. Prior to determining if a process is in control, you must first confirm that the process is capable of meeting specification Question 17 Identify all the statements below regarding control charts that are True: Variable control charts work in pairs. One controls for the central tendency of the process while the other controls for the variation within the process The key concept of rational subgrouping is that the variability within a sample should be minimized resulting i a homogenous sample A control chart is constructed based on acceptance sampling requirements If a process is in statistical control, it will never produce a unit outside of the control limits. Identify all the statements below regarding control charts that are False: A defective unit can have multiple defects The primary objective of SPC is to remove all defective units from a production lot prior to shipment to the customer. The X-bar and R chart should be used for variable data whose sample size is between 2 - 9. Having data outside the control limits is the only criteria to confirm that a process is out of statistical contro
