Tyre Size. Blood pressure is the term used to describe the strength with which your blood pushes on the sides of your arteries as it's pumped around your body. Once control limits are established, they should only be recalculated when a deliberate process change or improvement is introduced. Peterson and Brown (2005) suggest a procedure for converting standardized β weights to r, if the β weights range between -0.5 and 0.5. r can then be used directly as an effect size or converted into d or other metrices. Once you create a control chart using QI Macros, you can easily update the control limits using the QI Macros Chart Tools menu. If the Range Chart looks okay, then calculate, plot, and evaluate the X Chart.
