Have you ever had the perfect data science experience? The data pull went perfectly. There were no merging errors or missing data. Hypotheses were clearly defined prior to analyses. Randomization was performed for the treatment of interest. The analytic plan was outlined prior to analysis and followed exactly. The conclusions were clear and actionable decisions were obvious. Has that every happened to you? Of course not. Data analysis in real life is messy. How does one manage a team facing real data analyses? In this one-week course, we contrast the ideal with what happens in real life. By contrasting the ideal, you will learn key concepts that will help you manage real life analyses. This is a focused course designed to rapidly get you up to speed on doing data science in real life. Our goal was to make this as convenient as possible for you without sacrificing any essential content. We've left the technical information aside so that you can focus on managing your team and moving it forward. After completing this course you will know how to: 1, Describe the “perfect” data science experience 2. Identify strengths and weaknesses in experimental designs 3. Describe possible pitfalls when pulling / assembling data and learn solutions for managing data pulls. 4. Challenge statistical modeling assumptions and drive feedback to data analysts 5. Describe common pitfalls in communicating data analyses 6. Get a glimpse into a day in the life of a data analysis manager. The course will be taught at a conceptual level for active managers of data scientists and statisticians. Some key concepts being discussed include: 1. Experimental design, randomization, A/B testing 2. Causal inference, counterfactuals, 3. Strategies for managing data quality. 4. Bias and confounding 5. Contrasting machine learning versus classical statistical inference Course promo: https://www.youtube.com/watch?v=9BIYmw5wnBI Course cover image by Jonathan Gross.

A very good and concise course that helps to understand the basics of the Data Science and its applications. The examples are very relevant and helps to understand the topic easily.
Another excellent Executive Data Science course. Brian gives clear and concise explanations of the ideal versus real world of the data science workplace.
This is a recommended course where you understand what are the requirements for a data engineer, data manager and data scientis
Highly educational course on the realities of data analysis. Many good tips for your own analyses as well as for managing others responsible for coherent and accurate analyses.
Many real life examples but in the courses the instructor introduced some new concepts which could be useful if get into more details of them.
The lecturer has obvisously been through all the issues and learnt about them, perhaps first hand. It was a delight! Thanks so much!
Excelente curso, el contenido me ha ayudado a mejorar mi proceso de análisis de datos y a entender el rol de los miembros de mi equipo.
It was kind of hard to understand as I did not have any professional experience in data science. But, I am sure I can work in a professional environment now with the teachings of the professor.
I like that this course examples the many ways an experiment/analysis can go wrong and how to address these issues. Very practical for the practitioner.
This course is very interesting and worthwhile. we are living with data in our real life. good lectures. thanks to all team.Dr DVNS MURTHY, DIRECTOR, BADRUKA COLLEGE, KACHIGUDA, HYDERABAD.
One more thing to add. The link to Study.com works. But Study.com wouldn't let me watch the whole video anyway; it requires registering and subscribing (after trial period is over). Not useful.
Wanted some practical examples - of calculating P values with sample set of data & analyzing/reporting on it with inference.

Brian Caffo does a terrific job teaching some of more advanced material, I very much appreciate his jokes and humor, as well as his helpful explanations of the material.

Brian, Jeff, and Roger: Thank you very much for all the data science courses, really great. I generally rate them 5 stars. But for this one, I'm giving 3 stars, not because the content is not good (it is; it provides good practical and experiential information), but rather because the material seems repetitive at times either within the same course or with topics in the other courses. Also, the sequencing and lectures seem sometime a bit disjointed.
May I humbly suggest an idea: Integrate the key points of this course relating to real-world examples and the sharing of real-world experiences into one of the other courses.
Thank you.

I found this course to be notably worse than all of the others in the series. There is very very little practical content provided within the lectures. Way too many summaries or over-views of what's to come next without really getting into the nuances of what is discussed as a course topic. Way too much repetition of the exact same content, there is even repetition of content in this course that was presented in another one of the courses in the series. Many of the examples are purely meant as a comedic aside rather than actually functioning to discuss the topic with depth. E.g. - talking about statistical modeling and putting up a picture of Ben Stiller from Zoolander - then keeping the picture up there for the entire explanation. There's literally a Nic Cage example provided for the confounding factor lecture only for the instructor to say directly after "This isn't actually the best example" - then proceeds to not explain why it was brought up aside from mentioning there's a spurious correlation. Way too much repetition of similar examples - showing photos of a muscular v. skinny Christian Bale. This pop-culturey reference isn't needed in the first place and doesn't need to be shown in triplicate. I don't mind repetition if there is additional nuance or content provided through them, but that isn't the case in this course. I find there is too much focus on side tangents, where the instructor seems to change thoughts mid-sentence but forgets to come back to the original idea. I think that every single video could be cut down by 25%, purely by being more concise, and should include more nuanced descriptions. I found it particularly odd that instrumental variables were noted as a rather clever technique, yet an explanation was intentionally avoided, however an example was still provided. Bringing up a topic, intentionally refusing to define it, then providing an example directly after just doesn't make sense. I think that more time needs to be spent refining the lectures so that they're designed to teach content. It has the feel of someone who's talking about a field to get people interested in it rather than a practical training course. Many key terms are very poorly defined with examples (on many cases the audience is referred to wikipedia for explanations) in which the basics are repetitively explained while the nuances are glossed over. There seems to be an odd theme where summaries and over-generalizations are far too frequent and yet the key terms and how they relate to examples are an afterthought. I don't think the summaries are necessary given the fact that users can literally re-watch every single video and there isn't enough total content to justify a summary in the first place. Additionally, this course also seems to deviate from the others in that there is an assumption that the student has a heavy amount of programming experience already built in (or that's my assumption since many of the term explanations aren't discussed too heavily). Prior lectures break down the basics more and indicate that potential managers should pursue the data specialization courses.
great for existence human and android based life-form simulation internal lifestyle...
The course improves life within the simulation 10 fold at least(when combined with the other specialization courses) ...
Perfect learning tool for those who have worked professionally in research field sin our simulation and yet now have a touch of "the turrings" or you know : CBI...
Special thanks to the designers of the course.
Top scores for coursera.org &John Hopkins ...

Very nice and helpful course to understand how data science helpful in different perspective in our daily life. It helps me lot. Thanks to Team of Course and Coursera team.. Special thanks to Resp.Professor Brian Caffo for boosting the knowledge through different modules. I also Thank to Johns Hopkins University.. Always ready to do lots of course to enhance my skill in Data Science field.
Great information. For real newbies like me, might help to review basic concepts a few times (e.g. what does "p" mean? I know it was explained, but didn't grasp it the first time, helps if I hear it a few times, etc.) But, hey, you guys have done a fantastic job pulling all this together and teaching it at the 30,000 ft. view level. So great job.
At first it was hard to follow, because so many terminology I could not understand as from a non-data science person. But after week 2, it's super easy and Brian delivers it with passion plus so many anecdotes regarding to topics. Which really helps me digesting those "unknown" terms. Great job, I'm so pleased with this course!!
The topics were really well developed by the instructor, and the examples given by him were totally clear. As I am the cofounder of a computer vision and data science company, what I learned during this course is being very useful for me. I totally recommend it. You will need a basic data science knowledge though.
Excellent course! The only thing I would say is that many managers from the corporate field simply would find it too "academic". But this was a huge plus for me - and I think the course will serve extremely well also to anyone who works in academic research and has to handle some real-life data.
This class was bit more difficult than the previous ones and it requires really focused attention on understanding the subject matter. The course is intended to improve your understanding in subjects of surrogate variables, and how to become a better database manager. Excellent course!
As someone with a limited tech background but a basic understanding of statistics, this course really hit the mark when it comes to challenge and usability of the learned material. Also the instructors are good and moderatly funny, which is helpful in motivating my further learning.
Its an exceptional course. A must pursue course for every manager either as new learning or refresher of knowledge.
A great thanks to course trainers. Their teaching approach is very target oriented to put the concepts in student brain in simpler and efficient way.
I liked this course most of all the courses of this specialization course. The only difficulties I faced was all the examples were related to biomedical science, maybe a more general example would do better consideration for learners from other domains like me.
The other courses in the exec series are a little simple. This started to address some core analysis issues and how to address them in a real life situation. A good reminder and thought provoker on what should be trying to do within the enterprise
