Item Acesso aberto (Open Access) Análise do emprego do cálculo amostral e do erro do método em pesquisas científicas publicadas na literatura ortodôntica nacional e internacional(2011-12) NORMANDO, Antonio David Corrêa; ALMEIDA, Marco Antonio de Oliveira; QUINTÃO, Cátia Cardoso AbdoTo evaluate, quantitatively, how often the researchers of orthodontic science have used the calculation of sample size and evaluated the method error in studies published in Brazil and in the United States of America.Item Acesso aberto (Open Access) A escolha do teste estatístico – um tutorial em forma de apresentação em PowerPoint(2010-02) NORMANDO, Antonio David Corrêa; TJÄDERHANE, Leo; QUINTÃO, Cátia Cardoso AbdoSelecting appropriate methods for statistical analysis may be difficult, especially for the students and others in the early phases of the research career. On the other hand, PowerPoint presentation is a very common tool to researchers and dental students, so a statistical guide based on PowerPoint could narrow the gap between orthodontist and the Biostatistics. This guide provides objective and useful information about several statistical methods using examples related to the dental field. A Power-Point presentation is employed to assist the user to find answers to common questions regarding biostatistics, such as the most appropriate statistical test to compare groups, to make correlations and regressions or to look for casual and systematic errors for a specific method. Assistance to check normal distribution and to choose the most suitable graphics is also presented. This guide could be even used by reviewers in a quick assessment to check the appropriated statistical methodology into a specific study.
