Abstract
Initial data analysis is conducted independently of the analysis needed to address the research questions. Shortcomings in these first steps may result in inappropriate statistical methods or incorrect conclusions. We outline a framework for initial data analysis and illustrate the impact of initial data analysis on research studies. Examples of reporting of initial data analysis in publications are given. A systematic and careful approach to initial data analysis is needed as good research practice.
