Final Exam - ME LAB 1

The science of measurement and can sometimes be overlooked despite being an essential aspect of manufacturing.

A standard that is sufficiently accurate such that it is not calibrated by or subordinate to other standards.

Determines the uncertainty (error) of a measurement device by comparing its measurement with the appropriate measurement standard.

The documentation of the calibration.

The difference between the true value and the measured value.

Caused by underlying factors (extraneous variables) which affect the results in “consistent/reproducible” and sometime “knowable” way.

Show no reproducible pattern and sometimes referred to as “noise”.

A science of collecting and analyzing data to identify trends and patterns and presenting them.
