of how much a test result might deviate from its "true value"—which is theoretically unknowable—within a specific confidence level, usually Key Pillars of Measurement Uncertainty
These are unpredictable variations that cause data to scatter. PTC 19.1 quantifies this as Random Uncertainty
Even with the PDF in hand, engineers make critical mistakes:
