Mar 9, 2011 the three basic principles of statistical design of experiments are control, randomization and repetition.
Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data. In applying statistics to a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model to be studied.

Moreover, statistical techniques are invaluable for assessing the significance of patterns or correlations. In engineering, mathematical and computational representations of established relationships and principles are an integral part of design. For example, structural engineers create mathematically based analyses of designs to calculate.
Purpose of statistical analysis in previous chapters, we have discussed the basic principles of good experimental design. Before examining specific experimental designs and the way that their data are analyzed, we thought that it would be a good idea to review some basic principles of statistics.

The statistical ensemble is a probability distribution over all possible states of the system. In classical statistical mechanics, the ensemble is a probability distribution over phase points (as opposed to a single phase point in ordinary mechanics), usually represented as a distribution in a phase space with canonical coordinates.
– randomization allows the later use of probability theory, and so gives a solid foundation for statistical analysis.
