What the fuck is this? > Mr. Wurtzel provided data from a firm named Symphony Advanced Media, which uses audio content recognition installed on phones to recognize what is being watched and when. According to Symphony’s data, the Netflix show “Jessica Jones” was viewed by 4.8 million people [...] http://www.symphonyam.com/technology/ http://www.symphonyam.com/technology/ apparently... edit: ah, I found http://observer.com/2016/01/netflix-hulu-data-symphony-advanced-media/ http://observer.com/2016/01/netflix-hulu-data-symphony-advan... > The company has over 15,000 viewers now and expects to hit 20,000 media insiders this year So they have 15,000 people running their spyware and they extrapolate the data out to 4.8 million people.

I don't know how robust their sampling method is, but how many samples do you need in a survey to do that level of extrapolation? I was under the impression that the political surveys extrapolated with less than this.

  The answer is: it depends. I remember the lesson my Stats teacher: How many Martians do you have to measure to determine the average height of a Martian? What if I told you that all Martians are exactly 6 feet tall? The correct way to sample to is to determine the variance in the population. If there is no variance, sample size needs to be only one. If not, there are statistical charts that tell you what your sample size needs to be to have some specific confidence that some percentage of the time your sample will be representative. If your population has a Normal distribution, you can use a Z chart to calculate sample size. Believe it or not, for normal distributions and command variances, a population below 200 is all that is necessary.

  There's a difference between random dynamic sampling and fixed sampling. Not that I think sampling is ever done very well in surveying, not that it's the most serious problem.

And they are "media insiders". Hmmm. Sounds fishy based on the context. No effort to distinguish if they mean people from media organizations, which is the meaning I take, or that they are in the know about media and content, which is not the meaning I get. Another bullshit company trying to make a name for itself bringing up the name of a successful company in its PR. I'll believe any of what they say when Netflix corroborates.

It has been known for awhile that many companies are using your phone to spy on you for a variety of purposes like that. Your smartphone is being used to observe and record your actions. Normally not a huge deal but sensitive conversations, etc. you don't even want it in the room with you.

Yeah, googling found a similar article: http://www.dailymail.co.uk/sciencetech/article-3401382/Is-phone-spying-App-taps-handset-s-microphone-listen-Netflix-viewing-habits.html http://www.dailymail.co.uk/sciencetech/article-3401382/Is-ph... Seriously, I have to root my phone to get all kinda of basic sane functionality, but running the mic 24/7 is okay?
