Clearly people love the iPad (although my needs differ) and have found workarounds for some of its limitations for use as a desktop replacement. Yet I can only imagine this "device" as primarily a desktop replacement using touch on iOS instead of OSX and K/M. Secondarily, some folks will detach it from a lightweight keyboard (Apple's own design) for meetings, presentations, moving around the house, etc.   It may not make use of multiple app windows simultaneously, yet...
I do know all that. Calculating margin of error is one of the most basic of 100-level statistics. You wrote: "All of this assumes the sample was truly random; but there's no reason to assume it's not, unless otherwise known." Wow. Really? Understanding how to calculate a simple statistic using division and square root, yet not knowing how to challenge basic assumptions in absence of any documentation of methods is an error that usually, godawfully, is present in a great...
Despite what you might think, I don't jump when people like you say jump. I have nothing to prove. What I will say is that margins of error mean nada when there is no data AT ALL about the population that provides context for a statistic. Furthermore, an N of 400 is uninterpretable when the size of the population and characteristics of the sample are undefined. Anyone can play with sample size to increase power and artificially boost significance. And IIRC, in some other...
@anadtksundaram: Wrong. My interpretation of the data presented was completely sound. I have a social science doctorate. Any freshman in an intro stats class will know YOU have no idea what you're talking about.
I shouldn't have replied from my phone
@muadibe Nope. I'm a huge Apple fan as my posts here will confirm. I happen to think it's hypocritical for AI commenters to disregard bad statistics when Apple is seen in a good light and promote bad stats if they make Apple look good. But your guess was quite predictable.
Meh. That sample is far too small and non-representative to adequately detect a reliable and generalizable effect. The article itself has far too little information to glean any context about how the data was collected.
I agree that's the case with consumer (especially mobile) products. Institutional budgets tend not to revolve around the fall/holiday buying season. More often, it seems, Apple is willing or forced to release desktops and notebooks away from the holiday schedule. They SHOULD release new Macs in the Spring and perhaps also the 6" iPhone and 12" iPad, as these may be more expensive (not holiday gifts) and may be more desirable to education and enterprise. Additionally,...
Great points.
She was right. They did that with iTunes Radio.
