Several examples were presented in which errors observed with a homogeneous group of individuals in tasks consisting of a large number of simple performances were described by a negativebinomial distribution. As the number of errors made by each individual has a Poisson distribution, the possibility of restoring the distribution of individual parameters from the group data was discussed. The possibility of testing on site was also pointed out. If applicants are tentatively assigned to a task, it can be decided according to the sequential analysis scheme on the records of actual daily performances whether each applicant should be finally assigned to the task or not.
