These particular tables are calculated using the “population adjusted hypergeometric distribution” (sometimes called “hypergeometric distribution”). The calculations are performed using a variation of the Clopper-Pearson exact method to calculate confidence intervals. Population sizes in these books range from one to 500. All integer population sizes are included between one to 250 after which the population size increases by 10 up to 500.
