Students of the Dutch bachelor’s programme, see Toetsende Statistiek

Entry requirements

This course builds on the Introduction to Research Methods and Statistics course, and presupposes the knowledge and skills taught there.


In this course the students’ knowledge of probability theory is refreshed and applied to the statistical tests most frequently used in psychology. The aim is for students to understand the following concepts: sampling distribution; statistical reliability; hypothesis testing; the principles and procedures for the various significance tests. Students learn to select and perform the appropriate test in a given situation.

Course objectives

  • Students will acquire an understanding of the concepts of sampling distribution, statistical reliability and hypothesis testing, as well as the principles and procedures of the various tests of significance.

  • Students will be able to select and perform the appropriate test in a given situation.

  • Students will acquire skills in working with statistical software used for these tests.

A complete list of course objectives for this course is available on Blackboard.

Lectures Work group sessions Exams



The Student Services Centre enrolls first-year students in lectures and work groups. However, students must register themselves in exams.
After the first year, students must register themselves in the first year course component they need to repeat: lectures, work groups and exams. A second (or higher) year student who needs only to repeat the SPSS skills test is required to attend the four SPSS work group meetings again. As such, he/she must also register again for these SPSS work groups. Enrolling for workgroups


Students are not automatically enrolled for an examination. They can register via uSis from 100 to 10 calendar days before the exam date; students who are not registered will not be permitted to take the examination. Registering for exams

Mode of instruction

8 lectures of 2 hours and 8 work group sessions or more of 2 hours.
At the end of the week additional work group sessions are organized.
Active participation in the work group sessions is mandatory.
The lecture is recorded and available as weblecture.

Assessment method

  • A written examination consisting of 40 multiple-choice questions, each with 4 alternatives, covering both theory and statistical calculations from the literature, the work group sessions, and the lectures.

  • An SPSS skills test covering the various aspects of students’ skills in working with SPSS as well as describing and interpreting analysis output.

The final grade will be a weighted average of the examination grade (70%) and the grade for the SPSS skills test (30%).

Regulations on grade calculation

The Faculty of Social and Behavioural Sciences has instituted that instructors use a software programme for the systematic detection of plagiarism in students’ written work. In case of fraud disciplinary actions will be taken. Please see the information concerning fraud.
