Systems and methods are provided to enable viewing and computation of differential data for an item or item subset when compared with other items or subsets. A score may be determined for an item or subset where standard deviations and distance metrics are computed to determine differentiators. In one aspect, a system for comparing data items is provided. The system includes a weighting component to determine a score for an item or subset of items. A differentiator component determines a comparison metric for the item or subset of items based in part on a distance metric to at least one other item or subset of items. A user interface can be provided to display the comparison metrics.
