1. Calculate the control limits.

• Determine if any points are out-of-control.
• If so, remove those data points and recalculate the limits.
• These become your established limits and will not change when you add the additional 5 data points.

2. Once you have established your limits, collect five more data points to "test" these limits. Do not recalculate the limits based on the additional data points

3. Most importantly, using excel create either a p-chart or moving range chart depending on your data.
