I find it curious that there are so many courses for data-science related subjects, which superficially seem to cover the same material, and relatively few courses covering more traditional CS topics such as computer systems, networks, OS. I suppose it has to do with the market, but also feels like colleges are skating to where the puck is, rather than where it will be (or perhaps, where it could be).

Because it sounds cool...I remember when I was applying for college (2001), nanotechnology and biomedical engineering was all the rage. Glad I stuck with electrical engineering.

Or bioinformatics ~2009?

There are at least two big turn-offs to this course at first blush: 1) they insist on using anaconda (effectively another package manager complicating the already layered interaction of system pip, virtualenv, virtualenvwrapper etc ). 2) they use Microsoft VisualStudioCode (so, inevitably a good deal of time in this course will be spent learning how to navigate a bloated IDE)

People at Berkeley view this class as kind of a joke. The average grade is insanely high and the topics are covered in much less depth than just the normal intro cs or stats classes. https://www.berkeleytime.com/grades/?course1=7765-all-all

The instructors have explicitly said, if you have previous CS or Statistics knowledge, the class isn’t for you. This is for people who don’t know how to program and haven’t taken a statistics course yet.

I code myself. I've watched it. Pretty good learning platform (never had a look at a MOOC before): I am impressed (but I will take a look at other MOOCs mentioned in this discussion and I will certainly be less impressed very soon). Finished the first week. Right now, I find it a good introduction for someone who has no knowledge of code and statistics. IMHO, the main advantage would be that such a person may learn what coding and statistical reasoning looks like. The main disadvantage would be that this person think he has learned enough and keeps not trying to learn more about those topics. What an enlightening free week for the people: first look at "Do you trust this computer?", then attend this MOOC "Data8.1x"?

I disagree with this. Every enterprise company has an analytical department, even more so in the public sector. My municipality has 8 guys working on analytics for instance. They are mostly economics or (I’m not sure what it’s called in English, but it’s a degree in societal administration), but they really ought to be data scientists because everything they do is based on huge sql data sets. We pay private contracto…

My municipality has 8 guys working on analytics for instance. Do you propose that they should take a MOOC like this one, or that they should be replaced by MOOC graduates?

I think they’ll be replaced with candidates that mix economics and data science as they naturally retire or go elsewhere. If I was young in the field I’d definitely take a degree in data science, especially if I worked in the public sector where we’re much more willing to pay for your education as well as give you time off to take it.

Neither of which are the least bit consequential for anyone more interested in learning about data science.

US$65K for tuition

LOL. As someone from third world where local currency is enormously devalued with respect to US$, I wonder why would anyone do this?

If you think that's bad look up Executive MBA programs. Corporations basically give a university a nearly six figure donation for their top executives to get a tax-free tuition benefit for a rubber-stamped MBA largely indistinguishable from a real MBA.

I know the above probably sounds like sour grapes, I don't have an MBA or any graduate degree, I just think the whole Exec. MBA thing is a total scam against the companies paying for them and a huge cash cow for universities.

This is a general issue i have seen as well. We live in 2018 and there is no open source course for everything. Instead there are probably 10-30k universities who have similar courses and professors who give the same lecture every year. They get paid often enough by countries to create and do those courses. In germany most of our unversities are paid by all of us germans anyway. And what do you find online? Always th…

Exec MBAs are not for top execs. "exec" is just the marketing tag. It's exactly the same as exec Masters that GATech and UW do to extract tuition reimbursement funds from big companies like Microsoft

Okay, here's a view of what appears to be part of the course: We have a course (right a school application of stuff taught in school!) with two teachers, that is, two sections of the course, each section with its own teacher and its own students. At the end of the two courses, that is, the two sections, we want to compare the teachers. So we give the same test to all of the students from both courses. Suppose one sec…

What you are describing is known as bootstrapping (if sampling with replacement) jackknifing (if sampling without replacement), or (in the case you want to run a significance test, and not simply create a distribution or stats like confidence intervals) a permutation test. I think you already know that; I'm just mentioning in case others want to look these up by name. Also while they can be called 'distribution free'…

Whg is stats full of goofy names to make everything sound more unique and complex than it is?
