How to Create A Control Chart – Excelchat

We can use the statistical process control chart in Excel to study how processes or data changes occur over time. The Control chart has four lines including; a straight-line representing average, the data and a lower control limit (LCL) and an upper control limit (UCL). In this tutorial, we will learn how to create a control chart for analyzing data. Figure 1 – How to make a statistical process control chart in excel

Creating Control Charts

• We will begin by setting up our data as shown in Figure 2
• Column A will contain the Date (will not be used in creating control chart)
• Column B contains our Sample Data
• Column C will contain the Control Line ( Mean or Average)
• Column D will contain the UCL (Upper Control Limit)
• Column E will contain the LCL (Lower Control Limit)

• Figure 2 – Data to create a control chart

• Below our Table, we will set up a mini table. In Cells A14 and Cell A15, we will enter Mean and Std. Dev (standard deviation) respectively. Figure 3 – How to create a control chart

=B\$14+(B\$15*3) Figure 13 – Making a control chart

• We will use the Fill handle tool to fill the result down the column Figure 14 – Control charts in Excel
