Data screening, Advanced Statistics

The initial evaluation of the set of observations to see whether or not they appear to satisfy the hypotheses or assumptions of the methods to be used in their analysis. Techniques or methods which highlight the possible outliers, or, for instance, departures from normality, like a normal probability plot, are significant in this phase of an investigation.
