Biostatistics Consulting

Biostatistics consulting service

To improve the quality of animal research, we offer statistical methods consultation, including advice on study design, sample size calculation, methods for data analysis and reporting. We encourage you to consult us during the planning phase of your study, so that potential improvements 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. You can utilize our free service simply by fill in the online form "Request Animal Research Consulting".

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 standardized fee, for internal UZH researchers and external researchers. Contact Bernadetta Tarigan for more information.
