This course my favourite out of the 3 within the Epidemiology Specialisation.

It is a good course about validity and bias

Excellent. Bias, Confounding and Effect modifier are important issues to consider in a research. I indicate for all professionals to learn because is crucial to select scientific studies with confidence grade and as well do researchers more accurate.

Excellent series of courses. From discussing the types of studies, to evaluating the validity and bias in studies. Very pleased with the instructors. They explained everything very well. I liked the exercises that we did to cement the knowled

The course simple and clear provides efficient training for some aspects of statistics (esp confounding). Only what was little cons - I waited several days for peers' homework uploading, to review them. Overall - I recommend the course.

Overall great study experience! I would recommend this course to my fellow classmates.

A big shoutout to the Imperial College London team for making this specialization informative and valuable indeed.

The course was quite hard for me and challenging, but very useful. It covers all necessary topics, the presentation was understandeble with many examples.

Excellent concise course on the fundamental aspects of epidemiology related to validity, bias, confounding and effect modification.
