title: [Use of rough sets theory in analysis of qualitative data in toxicology studies].
abstract: In analysis of medical data a problem of simplified and not effective analysis of qualitative data is frequently encountered. This situation takes place particularly when data are measured in the weakest measuring scale--nominal scale. However this scale contains less detailed information than interval or ordinal scale, there exist a lot of different mathematical approaches to examine existing dependencies, among other causality. In this paper we present the exam-pie of usage of technique based on theory of rough sets to toxicological data gathered during mediumistic program "Throw smoking together with us" in 2000. The obtained results were compared with results estimated with alternative techniques published in [1].
