The upper control limit is calculated from the data that is plotted on the control chart. It is placed 3 sigma (of the data being plotted) away from the average line. The upper control limit is used to mark the point beyond which a sample value is considered a special cause of variation...
Upper and lower control limits are an important part of statistical quality control, an indispensable mathematical tool used in manufacturing and other disciplines. The limits tell a manufacturer if random variations in the production process are indeed random or if they arise from problems such as t...
Third, calculate the sigma lines. These are simply ± 1 sigma, ± 2 sigma and ± 3 sigma from the center line. + 3 sigma = Upper Control Limit (UCL) - 3 sigma = Lower Control Limit (LCL)Why are there so many formulas for sigma?The...
In the image below, you will see the calculation of TUR for a 100 VDC measurement with an upper tolerance limit of 101.1 VDC, a lower tolerance limit of 99 VDC, and an expanded uncertainty of 0.25 VDC (95% confidence where k=2). Since the tolerance is asymmetrical, you must first subt...

CP, or capability potential, is a measure of the potential capability with the assumption that the distribution of the sample process data is normally distributed and centered within the customer’s upper specification limit and lower specification limit. It represents the best the process capability...
This upper limit, known as BMI upper, is set at 25 kg/m². The BMI prime formula is pretty simple: Formula For BMI Prime = BMI/25. As it’s a ratio, BMI prime doesn’t have units. If your BMI prime is less than 0.74, you’re underweight; between 0.74 and 1 is normal; abov...
Since the upper limit for normal weight is often lower for Asian body types, the formula forBMI Primelooks like this: BMI Prime= BMI 23 Please notethat there may be differences in whichBMIis considered to be the upper limit for normal weight. ...
The program accepts values for subgroup size, number of subgroups, alpha for the X chart, and alpha for the v or √v chart both above the upper control limit and below the lower control limit. Tables are generated for specific values of these inputs. Comparison of the tabulated results to...
