Obs ppm below LCL represented by Oppm 100 then m = 100įixed specification limits must be outside fixed control limits and the target. Obs ppm above UWL represented by Oppm>UWL

Obs ppm above USL represented by Oppm>USL Obs ppm above UCL represented by Oppm>UCL Observed percent above upper warning limit. Observed percent above upper specification limit. Observed percent above upper control limit. The number of non-null values found in the data selected. Moving Range Upper Control Limit represented by MRUCL The Moving Range Average is based on succesive differences between individual values. The lowest value found in the data selected. If there is an even number of points the median is the average of the middle points.

If the number of points is odd the middle point is the median. Half of the points will lie above the median, and the other half will lie below the median. The median is a measure of control tendency derived from taking the middlemost or most central point in a set of sorted points. The highest value found in the data selected.

The Following changes with the release of Quality Window Version 5.0.0.783 Currently Reports as: Only entered values (non-null) are included in calculations in QW 5. These calculations are based on having a fixed USL, LSL and Target. This section is intended to provide a definition of terms used in QW 5 as well as information on the calculations and rules followed by QW 5 in developing the statistics that appear when a graph of a variable is displayed.
