Um estudo sobre a validação do tamanho da amostra em pesquisa estatística

Abstract

The current study makes an analysis of the sample size from an insufficient set of information, necessary for the determination of the sample size, using approaches obtained from the specialized literature. Two statistic research works of the biomedic area were used, although none of them tell anything about which method was used to obtain the minimum number of samples. The results obtained from the aproaches presented in this work are illustrated by the study of the cases. Their use could be considered in future confírmation studies of the sample size for statistic analysis.
