ELIXIR-EE training course on introduction to statistics in R. This course is designed to provide researchers in biomedical sciences with experience in the application of basic statistical analysis techniques to a variety of biological problems. The course extensively covers materials from https://sib-swiss.github.io/Introduction-to-statistics-with-R/

This course is a mixture of lectures and practicals. The main files for practising are the 2025-04-28-R-basic-stat.Rmd and day_2.zip. R markdown allows code (examples) and explanation / documentation to be in the same document in a nicely formatted, well structured manner.

Data files needed in the code are located in the data folder.

The lecture slides are found in https://zenodo.org/records/15294211

Learning outcomes:

  1. Have experience applying basic statistics techniques in R:

    • Learners will be able use R to run appropriate statistical tests and visualize these results.

  2. Summarize data with numerical and graphical summaries:

    • Participants will gain proficiency in ggplot library and learn to summarize data.

  3. Understanding basic concepts in statistics: one/two/multiple-sample tests, hypothesis testing, multiple testing correction etc.:

    • Trainees will be equipped with the knowledge about which statistical test to apply and when, how to do hypothesis testing in biological context and when to apply multiple testing.

  4. Learn about the relations in the data using correlation, regression:

    • Learners will find out about relations between features in data.

  5. Understand how to deal with categorical data in statistics:

    • Learners will gain understanding about how to find statistical significant associations in categorical data.
