Coefficient of Variation for Different Normalized Data Sets. The CV values for the three different normalization methods on the PMA dataset are represented here in a barchart. The CV for the non-normalized (raw) dataset is included as a reference. The quantile method is associated with the lowest CV, implying the greatest reduction in technical variation in the data.
