  1. improve Data Science 101 - Module 1

    None of the links to the reading material actually work, I tried the links for Modules 1, 2 and 3. One of the discussion topic responses in Module 1 suggests a link to Google where a sample Chapter 6 of the book is available, but the Review Questions require answers from other Chapters, e.g. the question re Walmart is not in Chapter 6 but in Chapter 1. The selection of answers to the New York Times question do not match the actual article from April 2015 (can easily be found using Google).
    Overall I'd say this course is a disappointment…

  2. Use a Spellchecker Before Publication

    In "Data Science Methodology", there are too many grammatical errors and answer errors in the reviews and exam for me to type out.

    Before a class is published online, it should have at least passed a basic spell and grammar check. It looks unprofessional.

    My suggestion is:

    Use a spellchecker before you upload it online. Also, at least one person should go through the reviews and exams to check if everything "looks" okay.

    I wanted this course to be supplemental material for my students. But the way it is now, I cannot suggest "Data Science Methodology" to them.

  6. Module 5 in Data Privacy Fundamentals

    I don't understand what the Review Questions in Module 5: Analyzing Hacked Passwords in R had to do with the subject matter of the Module. The first question asks which programming language is best for text analytics. R isn't even an option. It makes no sense. It wasn't covered in the module. Why even ask that?

  8. give an alternative for ibm.box.com

    Hi,
    could you please reconsider having your files (images and pdf's) on your server -bigdatauniversity.com- instead of ibm.box.com ?

    Eventually please add a pure text transcript as an alternative.

    due to the company policy I have blocked any pages with file-sharing, so I can not see the images in test questions and can not view any files hosted on ibm.box.com

  9. Automatically check exams after time runs out

    I though there is an automatic checking after the time runs out on Timed Final Exams. I answered all the questions but the scores were zero because I didn't check it one by one. I earned a Badge but there was no certificate issued. How sad? :( I got frustrated.

  10. Use Open Source Software for Predictive Modeling Fundamentals I course

    All the software needed in previous courses was open software or was free available for different platforms. In this course I find I must download a Windows or Mac version which does not work in my Linux machine, so I should install it in a VMBox. In addition, when I want to use it in the future to explore it and improve my knowledge about Data Mining I will have to pay for the SPSS Modeler.

    Despite of it, I find these courses really interesting, congrats for the project, it is a good way to introduce yourself in the Data…

  11. I din't pass the final exam because of Internet Connection and...

    Question is I have bad Internet Connection, and when I was answering some questions I clicked check but web didn't show me results. I tried to re-click again. Lag worked at that time and my second click was picked by web and my second opportunity was spent. This happens to me many times, and happened to me when I was doing Data Science 101 exam.

    One suggestion I propose is disable double-check when the first attempt is correct.

    I had a 59% score in Data Science 101. That means I can't achieve the Data Science lvl1 and Data Science lvl2…

  13. review questions

    If you miss a review question after two attempts, the correct answer is still not shown, just a red x on the wrong answer. Please show the correct answer.

  14. provide answers to the blanks in the slide presentations in the labs

    I have completed the first 3 modules of Data Science Methodology. The only resource I can find in these labs is what seems like a PowerPoint presentation in pdf that is based on something, but the something seems to be missing. I intuitively answered all but one of the review questions, but I definitely feel I'm missing relevant information because it is not provided.

  17. add an autoplay feature

    It might be nice to 'autoplay' a module instead of having to click for the next video. Or possibly add a next arrow at the lower right of the video?
