Introduction to Research Methods and Statistics
Experimental and Correlational Research (or similar courses)
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.
Learn about the many choices that need to be made during an investigation;
Learn about pitfalls in an investigation and how to guard against it; and
Acquire the skills required to make research reproducible.

Registering for exams
Mode of instruction
4 2-hour lectures
8 2-hour computer labs
2 graded assignments each weighting 35% of the final grade and a multiple choice exam weighting 30% of the final grade.
The Institute of Psychology uses fixed rules for grade calculation and compulsory attendance. It also follows the policy of the Faculty of Social and Behavioural Sciences to systematically check student papers for plagiarism with the help of software. Disciplinary measures will be taken when fraud is detected. Students are expected to be familiar with and understand the implications of these three policies.
