Exploratory Factor Analysis and Confirmatory Factor Analysis are two of the most common data reduction techniques that allow researchers to create scales from responses on the initial items.Advanced statistical methods include the opportunity to discover previously unidentified or unexpected relationships between items or constructs.It also may allow for the development of subtle items that prevent test takers from knowing what is being measured and may represent the actual structure of a construct better than a pre-developed theory.
Common formats for these norms include percentile ranks, z scores, sten scores, and other forms of standardised scores.
