Six Sigma Green Belt Exam Prep

Answer: B - Precision is the ability of an electronic scale to measure substances consistently every time the measurement is made.
Key Takeaway: Precision in measurement systems analysis is an important test of how well measuring equipment can consistently take readings. For example, if an electronic chemical is used to measure the weights of minute substances, the scale must provide consistent readings every time the measurement is made. An imprecise machine does not provide trustworthy measurements. To check for precision, multiple readings of the same materials are taken and the deviations of one reading from the others are measured.
