Der arithmetische stichprobenmittelwert (¯) (im englischen „ x bar “ gelesen, daher der name; The range (r) chart shows the variation within each variable (called subgroups). Web x bar r charts are the widely used control charts for variable data to examine the process stability in many industries (like hospital patients’ blood pressure over time, customer call handle times, length of a part in a production process, etc). Steps in constructing an r chart. Key output includes the xbar chart, r chart, and test results. Process that is in statistical control is predictable, and characterized by points that fall between the lower and upper control limits. Web an xbar chart is a graphical representation of the average value of a data set over a period of time. Web the ¯ and r chart plots the mean value for the quality characteristic across all units in the sample, ¯, plus the range of the quality characteristic across all units in the sample as follows:
