Langton-accordance and Concordance Tool
This tool has been set up by S Langton, who kindly accepted it to be published on ISTA web, based on his publication “Analysing collaborative trials for qualitative microbiological methods: accordance and concordance" published in International Journal of Food Microbiology 79 (2002) 175– 181. It is very useful for calculating accordance (repeatability) and concordance (reproducibility) for qualitative results obtained during CT and PT.
