I've never seen any evidence of samples or example systems.
The size of the sample is less important than its structure.
Analysis of a sample can cost anywhere from $30 to $100.
As part of a sample, you represent many other people.
Analysis of the samples will then start, with results published in late 2013 or early 2014.
Many others will join in the analysis of the samples.
The first step in analysis is the introduction of the sample.
The whole idea of a survey and a sample has completely gone over your head hasn't it?
Problems are found in less than 1 percent of the samples, department statistics say.
However, if the test is significant then a difference exists between at least two of the samples.
