Biostatistics for Plant Biologists


29-30 April 2019


Michael Hothorn, Prof., UNIGE
Marie Barberon, Prof., UNIGE


Ludwig A. Hothorn, retired Professor from the University of Hannover, DE


The 2 day course module will combine lectures and hands on practical sessions, covering the following topics:

1. Introduction to biostatistics and the importance of statistical software (using R!)
2. Statistical guidelines for publishing in high-ranked journals and their implications for data collection and analysis
3. First step of modeling: data structures in EXCEL (flat file format, unique sample ident, repeated measures, technical replicates, multiple factors) for an appropriate import into R
4. Graphical representation of grouped biological data using boxplots (R library(toxbox))
5. Introduction to different statistical tests using real life data sets from CUSO member groups: Two-sample tests (t, Wilcoxon, Chi2, ratio-to-control tests): p-values vs. confidence intervals (effect sizes), tests for data containing technical replicates (mixed effect model), estimation of the required sample sizes: experimental design, the power concept
6. Multiple comparisons: i) comparing several treatments or doses vs. control (wild type,..), ii) BenjaminiHochberg procedure for high-dimensional data
7. Exercise I - case study: root growth assay as described in Hohmann et al., PNAS 115, 13, 3488-3493
8. Writing statistical method sections, reporting summaries and presenting graphics
9. Exercise II - to be determined (a selected case study)
