For this project, we developed statistics and analysis tools associated with reputation on eBay to make feedback more useful for buyers and sellers. We created feedback scores base on the volume of each transaction. We then created reputation visulizations, namely volume sparklines and logarithmic stars. We also developed applications to compare proxy bids with the prices the items sold for in order to study causes of negative transactions. Finally, we developed a new system for sampling listings, weighted by volume.
