Standardized
Previous Top Next
In the standardized consensus analysis, the data is standardized prior to the PCA analysis.
Otherwise the analysis is similar, see Section Original.
Standardization of data is important, if it is suspected that some assessors avoids to use the
full scale or is disagreed with the other assessors on the span of one or more attributes.
Typically, results are improved by applying standardization, but not necessarily more correct.
