Hint: Use this chart to determine the Upper Control Limit (UCL) and Lower Control Limit (LCL) for an I-MR chart. Individual Moving Range (I-MR) chart is used when you have Continuous data with a Sample Size of one

Mean (x-bar)

Calculate the average of the entire data set and enter the value here

Average Moving Range

Moving Range is the absolute difference between two consecutive values. Calculate all moving range values and then calculate the Average Moving Range

Lower Control Limit (LCL) for Individual Chart

Upper Control Limit (UCL) for Moving Range Chart

Lower Control Limit (LCL) for Moving Range Chart

Control Limits

Control Limits cannot be calculated since a negative average moving range was entered. Enter a value greater than zero
