Chapter 5: Comparing the Measured Performance of Two Materials, Processes or Products
In this chapter, the authors consider the case of a chemistry lab tasked with regularly measuring the average atomic mass of silver samples. Since the lab in question had two mass spectrometers – a precisely calibrated new model and a slightly older model – the chemists needed to determine whether both instruments were performing at the same level. Though the problem in this case is specific, the solution illustrates fundamental techniques that can span industries. In this chapter, the authors provide step-by-step instructions on how to use JMP to perform significance tests to compare average performance and performance variation of two products, processes or materials.
