QUALITY_MAD#
Python object: phenotypic.schema._quality_mad.QUALITY_MAD
Measurement info for the replicate-agreement MAD QC check.
Documents the per-check extra columns produced by the median absolute deviation (MAD) agreement check, which gauges how tightly biological replicates or detection runs agree on a colony phenotype. The MAD is a robust spread estimate that resists single contaminated or mis-segmented colonies, so these columns help flag groups whose disagreement signals imaging artifacts rather than real biology.
