Statistical Process Control online Calculator

With the SPC Online Calculator you can easily input data and get accurate Statistical Process Control results without the complexity of traditional software. You can create the following control charts online with numiqo:

• I Chart Maker
• I-MR Chart Maker
• Xbar Chart Maker
• Xbar-R Chart Maker
• Xbar-S Chart Maker
• P Chart Maker
• NP Chart Maker
• C Chart Maker
• U Chart Maker

Therefore, to use the statistical process control online calculator simply copy your data into the table above.

When you create an Xbar Chart or an I-Chart you can run these tests:

• 1 point is more than 3 standard deviations away from the center line
• 9 points in a row on the same side of the center line
• 6 points in a row, all increasing or all decreasing
• 14 points in a row, alternating up and down
• 2 out of 3 points are more than 2 standard deviations from the center line (same side)
• 4 out of 5 points are more than 1 standard deviation from the center line (same side)
• 15 points in a row within 1 standard deviation of the center line (either side)
• 8 points in a row are more than 1 standard deviation from the center line (either side)

If you create control charts for attribute data these tests are run:

• 1 point is more than 3 standard deviations away from the center line
• 9 points in a row on the same side of the center line
• 6 points in a row, all increasing or all decreasing
• 14 points in a row, alternating up and down

Of course, you can also calculate the process capability with the cpk calculator.
