Subject Re: [QA] AOO 3.4.1 Performance Verification Test (PVT) Introduction
Date Sat, 07 Jul 2012 00:28:26 GMT
"Standard deviation" shows the how much variation exists from the average.
The smaller the "standard deviation" is, the more stable the test is.
In the PVT, we want to use the "standard deviation" to exclude the case
that one extreme value changing the average when doing a build-to-build
comparison.
