Dr. Carl Herrmann carl.herrmann (at)

Dr. Maiwen Caudron-Herger m.caudron (at)

The purpose of this course is an introduction to basic techniques of scientific data analysis, which every scientist will be confronted with. We will cover:

  • inference statistics (P-values, tests,…)

  • data modelling (linear/logistic regression,…)

Each lecture (Thursday) will be followed by a practical session (Friday) under R/RStudio
