To improve the quality of animal research, we offer statistical methods consultation. This includes advice on study design, on sample size calculation, on methods for data analysis and on reporting for publications, dissertations and theses. For master students seeking advice we suggest that the supervisor joins for the first meeting.
We encourage you to consult us during the planning phase of your study, so that potential improvements on research questions, study design and absolutely necessary numbers of test animals (3Rs principles: Reduction) can be made.
We provide a maximum of an hour appointment that is free of charge for animal researchers of UZH. The free 1h-consultation is per license or per study. Note that this 1h-consultation is NOT A VERIFICATION of experimental design & the planned statistical analysis of your application (new Form A, par 31). In the moment we do not have capacity for the verification.
We use and promote the free software R. We provide an interactive web app SampleSizeR to calculate sample size based on power analysis for confirmatory experimental designs.
We also offer "contractual consulting" and "contractual data analysis" with a fee, for internal and external researchers.
We offer biostatistics workshops for research group of UZH, from basic to advance topics. Examples of topics are:
- ANOVA and Hands-On Data Analysis with R (see testimonial),
- Important Families of Experimental Designs (completely randomized, randomized block and split-plot),
- Repeated Measures in Time.
- Other topics that your group might need.
The workshop is can be accredited as 0.5 day or 1 day of continuous education for persons involved in animal experiments by the veterinary office of the canton of Zurich. The workshop is with a fee. Contact Bernadetta Tarigan for more information.
