The main objective of scientific research is to solve problems. Empirical studies are affected by random and systematic errors. Random errors decrease the precision of study results, but do not bias these results. In contrast, systematic errors bias study results. Errors and methods to prevent and correct errors are introduced, and are put into the context of the different parts of empirical studies (i.e., research questions, literature review, sampling, operationalizations, design, implementation, data analysis, and reporting). |
