Event
F IGURE 3.3. The ability of each system to respondtoan event, for each of
50 events. Theevents havebeen sorted on thescoreallocated to System 1,
demonstrating thatinmost cases it hasoutperformed System 2.
Fig. 15.3 Revisualization. The simple act of sorting the points according to score achieved by one
of the systems shows how the performance of the systems compares. Even though System 2 is
occasionally superior, the lower graph clearly shows that System 1 is better in most cases
What is the population? How is a sample to be taken? What is the argument that
demonstrates that a sample will be representative?
How precise will the individual measurements be? How important is it to achieve
a particular level of precision?
What is the right way to summarize your results—an average? A median? A
minimum?
