Pitfalls of Data Analysis
Posted by Armando Brito Mendes | Filed under estatística
Como evitar erros e viéses na análise de dados
There seems to be a pervasive notion that “you can prove anything with statistics.” This is only true if you use them improperly. In this workshop we’ll discuss things that people often overlook in their data analysis, and ways people sometimes “bend the rules” of statistics to support their viewpoint. We will also discuss ways you can make sure your own statistics are clear and accurate. I will include examples from medicine, education, and industry.

What statistical analysis should I use?
Posted by Armando Brito Mendes | Filed under estatística, software
Excelente tabela de decisão sobre os métodos estatísticos com exemplos
The following table shows general guidelines for choosing a statistical analysis. We emphasize that these are general guidelines and should not be construed as hard and fast rules. Usually your data could be analyzed in multiple ways, each of which could yield legitimate answers. The table below covers a number of common analyses and helps you choose among them based on the number of dependent variables (sometimes referred to as outcome variables), the nature of your independent variables (sometimes referred to as predictors). You also want to consider the nature of your dependent variable, namely whether it is an interval variable, ordinal or categorical variable, and whether it is normally distributed (see What is the difference between categorical, ordinal and interval variables? for more information on this). The table then shows one or more statistical tests commonly used given these types of variables (but not necessarily the only type of test that could be used) and links showing how to do such tests using SAS, Stata and SPSS.

SPSS Web Book Regression with SPSS
Posted by Armando Brito Mendes | Filed under estatística, materiais ensino, software
Bom livro sobre regressão linear com SPSS
by Xiao Chen, Phil Ender, Michael Mitchell and Christine Wells (in alphabetical order) The aim of these materials is to help you increase your skills in using regression analysis with SPSS. This web book does not teach regression, per se, but focuses on how to perform regression analyses using SPSS. It is assumed that you have had at least a one quarter/semester course in regression (linear models) or a general statistical methods course that covers simple and multiple regression and have access to a regression textbook that explains the theoretical background of the materials covered in these chapters.
