Episode 0008: Misuse of statistics, and misunderstanding of randomness and probability

Misuse of statistics _________________ Clip from original episode A bit from the classic British show, Yes Prime Minister. _________________ Apple WWDC keynote  Apple CEO Tim Cook at this year’s World Wide Developers Conference Keynote. He points out that Apple has an install base of 80 Million Macs. Based on NetMarketShare data, as of May 2014, Windows 8 can be found on about 14 percent of all PCs currently running Windows. But with an overall market share of about 1.5 billion, Windows PCs represent nearly 91 percent of all computers in use worldwide. In simple terms, that means that Windows 8, widely considered a “failure” by critics and competitors, is in use on about 210 million PCs worldwide. That’s more than 5 times the install base of Mavericks, and more than 2.5 times the install base of every Mac currently in use. (Source: http://www.tekrevue.com/windows-8-outpaces-os-x-mavericks/) This also ignores other points of difference. Windows 8 is a major update that pretty much people only get with new machines and have to pay for. Maveriicks is a minor free upgrade by comparison.
