Abstract
Abstract The present paper reports on experiences gained, in practice, by the use of the statistic apparatus type 611 of the firm of Güttinger. By means of transmitting keys the transistorized calculating machine permits the determination of mean values and standard deviations of ten classes comprising 99 pieces each. It is demonstrated that several classes can combine and that piece numbers exceeding the mentioned limit can be adjusted by division without diminishing significantly the accuracy of the resulting values.
