Blocks Biased Blocks

Below is a list of the groups excluded from Blocks 14.2 (Mar 2006) because one or more blocks representing each group were judged compositionally biased based on the Biased Block Checker with column score cutoff = 0.50 and maximum clump size = 35% of the total columns.

These may not be the only biased blocks in the database. If others are causing you problems, please contact us.
