Process Sigma Level Calculators

Process Sigma Level Discrete Data Example

Click SigmaXL > Templates & Calculators > Basic Process Capability Templates > Process Sigma Level Discrete to access the Process Sigma Level Discrete calculator. The template gives the following default example.

Notes for use of the Process Sigma Calculator for Discrete Data:

1. Total number of defects should include defects made and later fixed.
2. Sample size should be large enough to observe 5 defects.

Process Sigma Level Continuous Data Example

Click SigmaXL > Templates & Calculators > Basic Process Capability Templates > Process Sigma Level Continuous to access the Process Sigma Level Continuous calculator. The template gives the following default example.

Note: This calculator assumes that the Mean and Standard Deviation are computed from data that are normally distributed.
