A control chart Excel process is a useful tool for studying how processes or other data changes over time. The chart consists of four lines -- the data, a straight line representing the average, as well as an upper control limit and a lower control limit (ucl and lcl in Excel).
B. Adding upper and lower control limits to the chart. After creating the control chart, you will need to calculate the upper and lower control limits based on your data. The upper control limit (UCL) is typically set at three standard deviations above the mean, and the lower control limit (LCL) is set at three standard deviations below the mean.
Ghost a Point - leave data point on a chart but remove it from control limit calculations; Delete a Point - remove a point from the chart and from control limit calculations; Recalculate UCL/LCL - recalculate control limits after adding new data; There are also options to easily re-run stability analysis after changing data or control limit ...
B. Explain the formula for calculating lower control limit in Excel. The lower control limit (LCL) can be calculated using the following formula: LCL = x̄ - A2 * R. x̄: the average of the data; A2: the control limit factor for the sample size; R: the range of the data; By using these formulas, you can easily calculate the upper and lower ...
