Mathematic Principles for Performance
Testers
statistical principles as they apply to performance test analysis and reporting.
managers alike need to know how to apply mathematics and interpret statistical data in
order to do their jobs effectively. Performance analysis and reporting are particularly
math-intensive. This chapter describes the most commonly used, misapplied, and
misunderstood mathematical and statistical concepts in performance testing, in a way that
will benefit any member of the team.
Even though there is a need to understand many mathematical and statistical concepts,
many software developers, testers, and managers either do not have strong backgrounds
in or do not enjoy mathematics and statistics. This leads to significant misrepresentations
and misinterpretation of performance-testing results. The information presented in this
article is not intended to replace formal training in these areas, but rather to provide
common language and commonsense explanations for mathematical and statistical
operations that are valuable to understanding performance testing.
