Inspection and testing are two of the most important activities performed by service centers. These activities involve the collection of two types of data: attribute data (go/ no-go information) and variable data (measurement information). When collecting variable data or measurement information, service center technicians obtain data consisting of two components – the actual value of the measured dimension and the error associated with the measurement. The service center should be focused on minimizing measurement error such that the measurement values are as close to actual values as needed to properly evaluate the measured item.
