Here's Why That BankMyCell iPhone Survey is Flawed

· · Link

An iPhone Survey from BankMyCell has bounced around the Apple blogosphere. It claims that iPhone retention is down 15.2% this year compared to last year. But The Macalope tells us why it’s flawed.

You can’t compare results for different demographies and declare them meaningful. You’re not controlling for anything…The only constant here is the gullibility (or culpability) of the technology press.

If BankMyCell were interested in meaningful results, it would have compared its own results over two years if it couldn’t get CIRP’s demographic breakdown. But it’s clearly not…If the methodology is crap, then you can’t trust the numbers.

That last line is the lesson we can learn from this: If the methodology is flawed, so are the results. You can’t p-hack your way around this one.

Apple Customer Satisfaction Scores 81 on ACSI Survey

The American Customer Satisfaction Index (ACSI) recently did an Apple customer satisfaction survey in which the company scored 81 out of 100. Other companies were included as well.

Following a 1% jump, Samsung moves into a first-place tie with Apple at 81 despite smartphone sales dropping for both companies…Apple’s iPhone X, iPhone 8 Plus, and iPhone SE all score 83…Customer experience shows little improvement over the last year. Cell phones are generally easy to use, with text messaging earning the top score at 85. Despite being the only area to improve year over year, battery life (78) finishes last among customer experience benchmarks.
