Quality

Quality is the number of parts that do not meet quality standards, and is calculated by Good Count / Total Count.

We already have Total Count, and we know that 8000 were returned dead.

1. Drag a new numeric to the right of quality called Dead Widgets
2. Drag a new calculation to the right of quality called Good Widgets
3. Link Total Count and Dead Widgets to the Good Widgets node and set the calculation for this to [Total Count] - [Dead Widgets]
4. Connect Good Widgets and Total Count to Quality and set the Quality calculation to [Good Widgets] / [Total Count]
