The workshop will be conducted online using a video conferencing tool. The following requirements are necessary:

Hardware:
- Macbook/Mac or PC/notebook with the Microsoft Office program.
- Camera (the cameras available with the above mentioned devices are sufficient)
- Microphone (the microphones available with the above mentioned devices are sufficient).
- The use of headphones is highly recommended to reduce echo effects.

Software:
- "Zoom" will be used as the platform for the workshop and video conferencing. This is free of charge for the participants. A one-time registration with an e-mail address is required.

More detailed information and instructions will be emailed to participants approximately two days before the workshop begins. Please also check your SPAM folder.

Concept of Workshop

In addition to a reasonable research question, every good and successful study needs above all a good experimental design. In order to create such a study, it is necessary to have a basic understanding of the interdependent interrelationships between the question, empirical hypotheses, study designs, error probabilities, sample size, measuring instruments (including test theoretical quality criteria), analysis methods (including their application prerequisites and their testing) and power considerations. Important issues here are, on the one hand, the operationalisation and specification of research questions, especially in the case of random sample numbers in clinical studies that cannot be freely selected, and the determination of the probable study design including the treatment of disturbing and moderating factors, and, on the other hand, the understanding of scale levels and the associated choice of analysis procedure, error probabilities and how to deal with them as well as effect strengths.

In the second part, an introduction to the basics of inference statistics will be given. (Clinical) Examples will be calculated using SPSS. Participants can bring and discuss their own (questions about) study designs.

Learning goals

  • Understanding the basics of inferential statistics
  • Understanding of the relationships between questions, empirical hypotheses, study designs, error probabilities, sample size, measurement equipment, analysis methods and power basic rules for reporting experimental design and statistics in scientific publications

Workshop content

  • Parametric procedures (assumptions, prerequisites, effect sizes and basic test procedures for interval data)
  • Nonparametric methods (assumptions, prerequisites, effect sizes and basic test methods for ordinal/nominal data)
  • Correlations (species and interpretation)
