title: [Nursing research and investigation statistics].
abstract: Research and investigation is an essential activity for nursing professionals. The evident increase in research and investigation by nursing professionals over recent years has not been exempt of difficulties nor limitations which pose obstacles for this research. We can mention the lack of a research tradition among members ot this professional group, the variability present in the formation of nurses in different nursing schools, and a deficit in professional development regarding methodological and statistical aspects. In this article, the authors debate some of the most frequent methodological and statistical problems detected in nursing publications in terms design, analysis and interpretation of results in research and investigation.
