It means when you drag and fill the remaining rows for column C all cells will be having the same formula as the one imputed in cell C2. The $ sign used in this formula is to make the rows and columns as constants. Step 3: In column C called Control Line, go to cell C2 and input the formula as =$G$1. See the screenshot of the partial data given below.Īfter applying the above formula, the answer is shown below. We will draw a Control chart to see whether the process is in control or not. We want to see whether the process is well within the control limits or not.
Suppose we have data of 30 observations from a manufacturing company as below. In this article, we are about to see how control charts can be created under Microsoft Excel. Though there are different Statistical Process Control (SPC) software available to create the control charts, Microsoft Excel does not lack in creating such charts and allows you to create those with more ease. If some of the points are lying outside of the control limits, the process is said to be not in control. If the control points are lying well within limits, then the process is controlled. It can be generated when we have upper and lower control limits present for the data, and we wanted to check whether the control points are lying between the actual upper and lower limits or going out of those.
