Most probable number definition

Most probable number or "MPN" means that the density or number of organisms per unit volume that, in accordance with statistical theory, would be more likely than any other number to yield the observed test result or that would yield the observed test result with the greatest frequency, expressed as density of organisms per 100 milliliters. Results are computed from the number of positive findings of coliform-group organisms resulting from multiple-portion decimal- dilution plantings most likely to be present in a water sample, and obtained from method-specific statistical MPN tables.
