  • A Crash Course in Data Science is a succinct, one-week overview of the field of data science produced by the same team from John Hopkins University that produced Coursera’s data science specialization. It is the first course in the “Executive Data S…
  • This short course is a great primer to both data science and the Coursera Specialization to which it belongs.

    This course provides a peek into what data science is like, but only gives a general picture in relation to some aspects. The topics were fine, but the quality of lecturing is bad with the lecturers being unclear with vague phrases. I would probably have learnt more spending the time reading an introductory book to data science.

    As a newbie to the subject this course gave me a concise introduction to it. I did all the modules in an afternoon (~4 hours). This was my first course on data science and I took it because I'm contemplating doing some more in depth, practical courses.

    Good high level overview -- lame that the quizzes are locked, there is essentially nothing to give you a sense of accomplishing anything unless you pay.

    Did whole course in one sitting. Will review whole specialization.
  • Not informative enough, consider it as a mediocre starting course in very good Executive Data Science Specialization. If you're going to take a whole specialization (which I recommend) – it's probably worth taking; as a standalone course – I don't think so.

    Very useful and valuable course for an Analyst. Easy material and documentations. Hope this helps for those who are looking for a Data Science but should be crisp to the point.

    Como um curso gratuito não era de se esperar muito mas, está com boas aparências e boa recepção.

    Através deste curso espero atingir grandes objetivos de empregos e investimentos futuros.
