Much of the information seemed overwhelming and not important at the same time. Personally, I felt the semantics of the definitions (data scientist vs data analyst) to be very boring and not particularly useful, and therefore could not remember the difference between the terms. The structure I like. The videos and explanations were clear. I enjoyed the course more when it went more into the graphs and process of machine learning. The questions just had to do mainly with memorization. The brief videos were not enough to engrain the terms and subtle differences into my memory. I failed almost all the quizzes the first time and had to retake them to get a passing grade. Maybe an aniki flashcard setup to prep for the quizzes would be a solution to get the buzzwords to stick in memory. I think I'll like the rest of the course better when the topics are more interesting and get more into specifics.
I really like the course, but maybe it is just the choppy audio (the voice is fine just the sudden start and start) or maybe it is just me and I am not in learning mood as (I am kinda tired) I am a little bored. Though, this is the introductory course so it isn’t to the interactive part of it yet, so that might be a thing which is fine. Without a foundation, how can you build a multistory house? I say 4 stars for several reasons. Not because of the course, though. Here is one example: Some people will not look at 5 stars and because of possible bias (and kinda the same with 1 stars) they will look at 2-4 star reviews first. (I am not saying this is a majority, just some). The course’s info-graph itself is going to be extremely helpful for remembering the terms, that doesn’t include the breakdown of the info graph and other information in the course.
In some questions the context was not immediately obvious to me - are talking about this info-graphic or the previous one? why is sales forecasting not ML? etc.. I have a feeling, that I would need more quiz questions to really solidify the new knowledge - for example I can repeat the examples about qualitative and quantitative analysis from part one, but I'm not really sure I got the principle right. It's really good that the course points out several times, that in many places these terms are being used differently - they really were in my previous company and it pops out in random places... I'm happy to be show other perspective.
Good course for understanding data analysis 👍
+: the content is well structured. - : the explanation is based on the flow of the data. the table brings several dimensions to this flow. all dimensions are not as important. it would be clearer with a graph with data associated to it than with a table: there is a lot of type of relations that are not very specific and fit in a table, and that are a lot clearer with another presentation. maybe it's a question of taste.
