On confidence intervals from micropalaeontological counts

Stefan A. Revets

Abstract. In micropalaeontology, statistics resulting from counts are rarely reported with error margins or confidence intervals. A short discussion of taxon proportions and of Fisher’s α diversity index is augmented with tables and graphs to assist the researcher in calculating confidence intervals. Any results, discussions or further calculations based on counts can then be put on a more secure statistical footing.
