Prof. Filippidis, your lectures are a thing to fall in love with. Thank you professor for such amazing lectures.

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

A very interesting and informative course evaluating confounding and bias in epidemiological research.

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

It is a good course about validity and bias

GREAT COURSE!

This course is an impressive conclusion to the Coursera Specialization where it belongs, and truly builds on the previous 2 courses (Measuring Disease in Epidemiology and Study Designs in Epidemiology). I would recommend this course to public health/epidemiology graduate students who need more material to understand the difference between confounding and effect modification.

This is such an amazing course which was really helpful for me in improving knowledge on the different types of bias in epidemiology and how to control them for increasing the validity of the study. The most appreciative thing is the opportunity provided here for learning from the examples given after each lecture and particularly the peer learning process.

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.

Very useful course mainly for understanding how to design correctly a study but also during analysis phase. It makes you reflect on aspects you might not consider by default. Fully recommended.

Highly recommended course. It may seem a bit short, but the videos explain the concepts in a clear, brief but very complete way. Definitely a course in epidemiology in public health.

Excellent course! If you expect to learn about epidemiological studies, their differences, grade of evidence and develop general knowledge on the subject I recommend this course.

Another great course from ICL! The course project in week 2 was very helpful: it solidified the concept of how to check for confounding. I highly recommend this course.

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

Good course for a basic understanding of epidemiological concepts that are generally hard to grasp.. Highly recommended for healthcare professionals.

amazing course that makes me love & enjoy epidemiology. Thankyou to all instructors!

Great way of teaching, I learned a lot through the examples presented. Thanks
