The paper deals with likelihood ratio tests for discriminating between two simple hypotheses based on grouped observations. The computation of the characteristics of these tests is considered. Corresponding efficiency criteria for grouped tests are derived based on statistical an information theoretical aspects. Numerical examples are presented for the normal and exponential distribution. They show that only a small number of groups is required to obtain tests having approximately the same statistical properties as in the non-grouped case if the group bounds are chosen properly. For sequential likelihood ratio tests based on grouped observations a direct method is presented for the computation of the OC- and ASN-function.
