ISO 21747 / DIN 55319 Process Capability Results - Specs Tab

Select the Specs tab of the ISO/DIN Process Capability Results dialog box to access the options described here.

Type

The Type box contains two options: Nominal ± delta and Lower, Nominal, Upper. Specify which method (see below) you want to use to enter the specification range.

Nominal ± delta

If you select Nominal ± delta (the default setting), Statistica expects you to enter the nominal target specification and the deviation (Delta) defining the specification range.

Lower, Nominal, Upper

If you select Lower, Nominal, Upper, Statistica expects you to enter the nominal target specification, lower specification limit (LSL), and the upper specification limit (USL). With this setting, you can define a specification range that is asymmetrical about the design center (nominal target).
