The course consists of e-learning modules, online ‘live’ lectures, short videos and online question hours.

The LUMC course ‘Basic Methods and Reasoning in Biostatistics’ covers the fundamental toolbox of biostatistical methods plus a solid methodological basis to properly interpret statistical results. The course is a mandatory part of the LUMC Graduate School Program and a prerequisite for any of the advanced biostatistical courses offered by the LUMC. This is a basic course, which targets a wide audience. The course is planned for a single week (+ preparation in the two weeks before), followed by a final examination on the next Tuesday.

Each day we start with an on-line lecture in Zoom, followed by a question hour for discussing questions on the e-learning. The rest of the day participants work individually through the e-learning.

The lectures cover the 'Reasoning' part of the course. Three lectures are mandatory: Study design, Good statistical practice and Multiple testing. Moreover, we offer two elective lectures: for participants interested on this topic, we offer an advanced elective lecture on modern prediction techniques. Also, since many of the examples during the course stem from clinical research, one elective lecture dedicated to pre-clinical research is offered. The lecture slides as well as additional lecture materials will be made available electronically at the end of the course (check the 'lectures' folder at the Section 'Course material').

In the short videos (about 10 minutes each), several experts discuss further on the 'reasoning' topics such as study design, bias, p-hacking, publication bias, good statistical practice, sample size calculation, pros and cons of p-values. In the e-learning part of the course, we will cover the basic methods of data description and statistical inference (t-test, one-way ANOVA and their non-parametric counterparts, chi-square test, correlation and linear regression, logistic regression, introduction to survival analysis and introduction to repeated measurements). For participants who are new to data analysis, the e-learning offers step-by-step guidance on how to perform these procedures in SPSS. Participants who are used to working with R can do the exercises in R instead of SPSS (note that answer models for R are offered but not step-by-step guidance for R starters). Participants who have already studied the e-learning topics in previous courses can use the e-learning as a refresher and work through the modules more quickly skip exercises if wanted. An online forum is available within the e-learning for posing questions during the full week and during preparation.

You will get access to the e-learning modules by January 25th. You are advised to work through the first 5 modules of the e-learning before the official start of the course on February 8th.

Make sure you have either SPSS or R (according to your preference) installed on your computer to work through the e-learning. You can find an SPSS trial version at https://www.ibm.com/analytics/spss-trials. R is a free software environment and can be downloaded from the R project website. Contact the ICT department if you need help with the installation.


  • Secondary school mathematics. No prior knowledge of biostatistics required.
