How do I create a X-Bar and R Chart in Excel. How Do I Create X-Bar & Range Control Charts in Excel Using SigmaXL? X-Bar & Range Charts. Open the file Click on Sheet 1 (or press F4 to activate last worksheet). Click SigmaXL
Then just type your data into the yellow input area and the control charts, histogram, values plot and probability plot will be drawn to the right. You can also cut and paste data from another spreadsheet into the template: Sigma Estimator Formula. The X bar R Six Pack also lets you choose which formula you want to use for sigma estimator. Creating a Control Chart. The Control Chart Template above works for the most common types of control charts: the X-Bar chart (plotting the mean of a sample over time), the R chart (plotting the range or Max-Min of a sample over time), and the s chart (plotting the sample standard deviation over time). This X-bar and R chart has room for up to 5 samples. The intent of the form is for the user to modify the scales on the left, then print it out for manual control charting. Note that no calculations are performed by this spreadsheet. It is a template of a form to be used to enter process data so manual process charting can take place in time. What is it: The X-Bar Chart is used to monitor the mean of a process over time for variations when the sub group sample size contains two or more variables. A control chart always has a central line for the average, an upper line for the upper control limit and a lower line for the lower control limit. The Xbar-R chart is used with variables data - data that can be "measured" like time, density, weight, conversion, etc. You subgroup data when use an Xbar-R chart. For example, you might be measuring the conversion from a batch reactor. You make four batches a day. You use those four batches to form a subgroup. x-bar,R chts Sample Data # of ounces in container Sample Sample Mean Range Control Limits, X-bar Chart Control Limits, R Chart LCL UCL Mean R-bar Factors n A2 D3 D4 X-bar and R Charts X-bar Chart for Mean Number of Ounces LCL UCL R-bar Range Days Range R Chart for Mean Number of Ounces.

x-bar and R Chart: Example The following is an example of how the control limits are computed for an x-bar and R chart. Note that at least 25 sample subgroups should used to get an accurate measure of the process variation. Xbar-R Chart. Xbar-R charts are often used collectively to plot the process mean (Xbar) and process range (R) over time for continuous data. This control chart, along with I-MR and X-bar & S, are used in measuring statistical process control and assessing the stability of a process.

X-bar is the sample mean calculated as the sum of the observations divided by the number of observations in the sample (n). The range for each sample is calculated as the Max value minus the Min value.
