Comparison and Selection of Populations with Special Reference to the Normal Distribution

Abstract

In this thesis, a confidence bound approach is enlployed to investigate the goals of comparison and selection of the t best populations, and silllultaneous conlparisons with a control and with the best. A particular case studied in detail is that of the nOrInal distribution. The robustness of one of the selection procedures to this assulnption of nornlality is also considered. Enlphasis is placed on the practical application of these goals and the proposed procedures, in particular to the problem of personnel selection, for which a detailed methodology is discussed.
