This chapter starts by defining the basic concepts: metric, measure, and measurement. It then introduces the different scales of measurement, allowing one to classify the types of values assigned by measures. Next, definitions of the most common performance metrics are presented. The chapter continues with a detailed discussion of the quality attributes of good metrics. Finally, the different types of averages are introduced, while showing how they can be used to define composite metrics and aggregate results from multiple benchmarks.
