  1. SQL 101, Module 5 audio and video disconnected

    Please check the vídeos I've quoted in the message title.

  2. The Data Science Foundation Path Does Not Make Sense.

    The Data Science Foundation Path Does Not Make Sense. It goes from a very basic (and good) introductory course discussing what data science is and how it can be used (a 101-level course), to the next course in the path with talks about using tools that an aspiring beginner does not understand, and furthermore, it speaks in a language beginners do not understand ("Jupyter is an evolved version of Python"---??? What does this even mean? What is Python; what is any of this?)

    This path is missing several steps between the first course, which is marked at having an audience…

  5. Big Mistake

    In video "ANOVA" at 3:51 there is a big mistake in my opinion because

    pvalue=1.0586193512077862e-11 not shown and the narrator said it is greater than 0.05 and this destroy the logic of the video.

    Kindly fix it fast.

  11. Problem Suspected

    Dear Support,

  13. Fix "elseif" on video for "Python for Data Science" (PY0101EN) - It should be "elif"

    In the video for "Conditions and Branching" the syntax for "else if" is incorrect. It is presented as "elif" (that's correct) and then it is called and shown in examples as "elseif" which is not allowed in Python. The right sentence is "elif".

    Hope it helps!

  14. Retake Exams

    The point of this site is to learn and I find it ridiculous that you cannot retake a course if you fail it. That does not encourage users to learn it only teaches that you should get it right the first time or quit. I now understand what I did wrong and would like the chance to prove so and receive the badge.

  15. Some issues...

    1 - There is something wrong with the user's session management, when browsing pages the account name on top-right always change to "login register" links;
    2 - The "claim you offer" button is not working, there is an error in its loading;
    3 - The link to open the account options (top-right) is kind of small, I always click on the name thinking that is going to open a menu and the page is redirected to the Dashboard;

  16. Pronunciation of 'Data'

    Hi, this could be a feedback but please bear in mind it may be very opinionated. I checked with several colleagues and none of them are comfortable with the pronunciation of the word 'data'. For me it is a very distracting part of the videos and I decided to turn off the audio due to that...

    I did of course look it up and the pronunciation can be:
    1. 'Big day-tah'
    2. 'Big dad-ah'

    Both are correct. The second one is however very uncommon and can be experienced as very distracting (in my opinion). I am writing this feedback to…
