Typically, a blocking factor is a source of variability that is not of primary interest to the experimenter. An example of a blocking factor might be the sex of a patient; by blocking on sex, this source of variability is controlled for, thus leading to greater accuracy." . <http://www.ebi.ac.uk/efo/EFO_0005067> <http://purl.obolibrary.org/obo/IAO_0000117> "James Malone" . <http://www.ebi.ac.uk/efo/EFO_0005067> <http://www.geneontology.org/formats/oboInOwl#hasExactSynonym> "batch" . <http://www.ebi.ac.uk/efo/EFO_0005067> <http://www.geneontology.org/formats/oboInOwl#hasDbXref> "NCIt:C25436" . <http://www.ebi.ac.uk/efo/EFO_0005067> <http://www.geneontology.org/formats/oboInOwl#hasDbXref> "NCIt:C48949" . <http://www.ebi.ac.uk/efo/EFO_0005067> <http://www.geneontology.org/formats/oboInOwl#hasDbXref> "NCIt:C61286" . <http://www.ebi.ac.uk/efo/EFO_0005067> <http://www.geneontology.org/formats/oboInOwl#hasDbXref> "NCIt:C86947" . <http://www.ebi.ac.uk/efo/EFO_0005067> <http://data.bioontology.org/metadata/def/prefLabel> "block" . <http://www.ebi.ac.uk/efo/EFO_0005067> <http://data.bioontology.org/metadata/def/mappingLoom> "block" . <http://www.ebi.ac.uk/efo/EFO_0005067> <http://data.bioontology.org/metadata/def/mappingSameURI> <http://www.ebi.ac.uk/efo/EFO_0005067> . <http://www.ebi.ac.uk/efo/EFO_0005067> <http://data.bioontology.org/metadata/prefixIRI> "efo:EFO_0005067" . <http://www.ebi.ac.uk/efo/EFO_0005067> <http://data.bioontology.org/metadata/def/mappingSameURI> <http://www.ebi.ac.uk/efo/EFO_0005067> .
