I just completed the Biostatistics specialisation, so I have posted these comments on all the courses:

What I most appreciated: Dr McGready is a fantastic lecturer, and I learned a tremendous amount from his lectures. I feel that you need to do all four courses to truly appreciate all the lessons.

What I think will improve the courses: There are some mistakes in the quizzes and the answer sheets, and I think it is because Dr McGready used the lectures that he uses in his classes at JHU, but had to transcribe the quizzes into the Coursera format. I feel that the lectures would have had even greater value if we got to program some of the statistics and manipulate some of the data in R or SPSS.

Overall, I really enjoyed the specialisation, and I certainly got what I was looking for. Thanks again for all your hard work!

This course is a good introduction to summary statistics that you might see in public health research. Covers normal distributions and standard deviation, binary data (risk difference, relative risk, odds ratio), and time-to-event data (IR hat, IRR hat, survival time/Kaplan Meier curve). The lectures are good and the instructor provides 'additional examples ' lectures. Some additional explanation of terms would be helpful. Course quizzes can be tricky - you have to type in something exactly as was entered in the key to get credit and the phrasing of some of the questions is confusing. Overall, a good intro to biostats.

Learned a lot of new concepts and refreshed the part of my brain that studied probability mathematics, etc as a highschool senior -- unfortunately, mathematics that seem to get abandoned during most of med school. Instructor guides you through the topics in a really intuitive way.

Admittedly, it seems as though the topics i was most curious about only appear in subsequent courses, so i am slightly disappointed. Hopefully future courses also come with a free trial!

Give it a shot to cement your understanding of stats as used in the news, and in public health in general!

I took the course to improve my competencies and build my capacity in biostatistics. This course has helped me to understand some biostatistical concepts that I did not fully grasp before now; e.g. standard deviation of binary data, some aspects of risk difference and relative risk and Kaplan-Meier plots. In fact, I'm impressed with the explanation of how to interpret risk difference and relative risk, i.e. for groups and individuals respectively!

Great intro to public health statistics, though the coursework needs a bit of a once-over for typos here and there, and the assignments could be more challenging, in order to better reinforce the concepts. As it stands, the lecture material is excellent, but the assessments are a bit repetitive, so your muscles aren't fully flexed and gaps in knowledge could remain.

Very comprehensive and informative course. It was easy to grasp because concepts were simplified and examples were shown for each topic. Some of my comments include the relatively long videos some of the lectures, which may be condensed or broken down further; as well as the use of pen marker during the lecture which is, at times, difficult to see or read.

Everything was good. Instructor is good but because online courses are some kind international, he should talk more slowly and more precise for international students. I know he is precise for English speaking participants. Anyway, his explanation and examples were very good. Thanks.

Excellent survey of statistical methods, interpretation and presentation. Prof. McReady's interest in and eagerness to share guidance on proper use of statistics in public health might convey better with improved graphics, but were on the whole very understandable and compelling.

Simplified explanation. Tests in the course really help you make sure that you have understood the concept. However the presentation of the courses should be more variable to avoid being monotonic. Definitely recommend for beginners: Understand basic concepts in biostatistics.

Very informative and practically applicable course. However, I struggled to understand the instructors speech and the way he phrased concepts at some points. Doing a quick internet search helped me understand the point he was trying to make in these instances.

Fantastic and inspiring course. Very essential for everybody in the field of public health. Prof. Dr. John is extremely lucid and clear. Additional information or any added reading materials might help the aspirants.

Excellent explanations and interesting quizzes. I really enjoyed the final project. There was some echo throughout the lectures which was somewhat distracting, but that's minor. Thank you very much!

I loved the profesor and the entire course. Many examples, simple language, great for understanding the basics of statistics. I'd have loved it if it contained more information about more subjects

Great course. Couple of hiccups along the way, but I think they are all ironed out now. The instructor is excellent at explaining and providing relevant samples to demonstrate course material.

There are some quizzes that only give me one option in the answer and is also a wrong option. This make me get a low grade. The rest of the element are great, I loved it.

it was a great learning experience and this coursehave provided insight into some vital concepts in biomedical health statistics,I am very thanful to the entire team.

I found it to be a really useful refresher from an introductory biostats course from my graduate studies. Thanks for making this information so accessible!

Quite a good course - sometimes though the questions are not really covered within the course lectures. Simple and easy to understand.

This course does a good job of covering the concepts and making sure you understand them without requiring much actual math.

I liked the course very much. It would be helpful if we can get some better explanations on the box plot data presentations.

In some areas to many unecessary words, it is easy to lose focus. Handwriting very bad!

But overall very good explanation.

Good course. But some of the questions are not understandable. And some of the calcualtions were not described detail.

Good course, would be great if typos/errors especially in week 4 quiz and final course quiz were corrected.

This was a pretty great course. I do not know why I bothered with getting a Masters degree honestly.

Very clear, but some concepts were quite basic and could have been explained more concisely.
