ABSTRACT
The statistical techniques that have been presented in this book are applicable to many of the situations that are encountered when dealing with ordinary measurement data. They are equally useful whether one is dealing with chemical measurements, or physical, or engineering data. They are, of course, based on the assumption that one has data that are worthy of statistical evaluation. That is to say, that data should be the output of a system under statistical control and should be reproducible and representative of what would be expected if that same set of measurements were undertaken again under the same conditions of measurement. The statistical techniques that have been presented provide the tools for deciding whether that is the case when replicate measurements are made.
