Good Research Practices


Entry requirements

  • Psychometrics

  • Multivariate Data Analysis


In the last decade several papers on questionable research practices (QRP) have appeared in the scientific literature. Although QRP differ from fraud, they nevertheless hamper scientific progress. In this course we point out the many choices to be made in any psychological investigation and the decisions that lead to best research practices. For science to make progress, it is important that an investigation be reproducible. Reproducible research refers to the idea that the ultimate product of academic research is a paper along with the full computational environment used to produce the results in the paper such as the code, data, etc. that can be used to reproduce the results. Besides reproducing the results this also offers the opportunity to create new work based on previous research. In this course students acquire the skills required to make research reproducible.

Course objectives

Students will:

  • Learn about all possible choices that need to be made during an investigation;
