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"?
