Big Talk About Small Samples 246

Bennett Haselton writes: My last article garnered some objections from readers saying that the sample sizes were too small to draw meaningful conclusions. (36 out of 47 survey-takers, or 77%, said that a picture of a black woman breast-feeding was inappropriate; while in a different group, 38 out of 54 survey-takers, or 70%, said that a picture of a white woman breast-feeding was inappropriate in the same context.) My conclusion was that, even on the basis of a relatively small sample, the evidence was strongly against a "huge" gap in the rates at which the surveyed population would consider the two pictures to be inappropriate. I stand by that, but it's worth presenting the math to support that conclusion, because I think the surveys are valuable tools when you understand what you can and cannot demonstrate with a small sample. (Basically, a small sample can present only weak evidence as to what the population average is, but you can confidently demonstrate what it is not.) Keep reading to see what Bennett has to say.

Your browser supplies HTML5 Geolocation. But it sounds like the submitter is having problems with GeoIP detection. That's a server-side issue and relies on subscription databases for identifying where physically on the globe an IP might map to. It's also horribly inaccurate as the submitter has found.

Short Answer:
Signup for a VPN or Proxy service with an exit point in the region you want.

Longer Answer:
IP-based geography detection (GeoIP for short) depends on the databases and services that various providers are leveraging. It's inherently inaccurate. Good luck getting these fixed as there are a bunch of different services (including the W3C) that you would need to get updated. Are you sure your routing exit point isn't actually in Ireland? My company's IP address maps to an exit point in San Francisco, even though I'm located in Los Angeles.

HTML5 location detection is pretty accurate, insofar as it relies on your browser to tell the site/service where you are. You should be able to force that setting in your browser.

You spend money on food regardless if you have any income. Ergo, food expenses are not direct costs associated with your income.

If you have to wear a uniform to your job, and pay for it yourself, then it is certainly tax deductible. Just like travel, meals, etc.

Rule of thumb - if you could do without it when unemployed, but it's required for your *particular* employment, then it's a direct expense that you can probably deduct.

Comment So, Moz has gone to the dark side. What about DDG? (Score 1) 327

Seems Mozilla has sold out. Which makes their choice of DuckDuckGo as default search engine interesting: have they sold out too?

The thing with DDG is, I'd be happy to believe their no-tracking pitch, but I can't quite understand how they're gonna make money out of a free search engine without it...

The problem is that most voters simply don't know what to care about. Voters worry about irrelevant issues like abortion, gay marriage, inequality, and racism, while not worrying enough about the stuff that matters, like banking regulation, tax policy, nepotism, and crony capitalism.

That's not true, and it's a tired trope I keep hearing over and over. Voters do care, but they care about different things. Some people care more about sociological issues, whereas others care more about socioeconomic issues.

Their month-to-moth offer is still Unlimited, and says so in the language. And I have the opportunity to sign a new contract, and lock in the same service (for example, to subsidize a phone).

They are trying to use contract language to redefine Unlimited to mean something other than Unlimited, but still call it Unlimited to avoid.

With current LTE speeds, it is possible to hit the "soft" threshold for a monthly data use in less than 90 seconds.

If they want everyone off the plan, they could change the terms and call it "Throttled" and not be lying. But they want to have their cake and eat it too. They know that if they truly ended the plans, customers would take the opportunity to walk to another carrier.

I have Grandfathered Unlimited with AT&T. They're screwing us.

Unlimited used to mean Unlimited. Now "Unlimited" means if you use more data than our basic tiered plan, we are going to arbitrarily throttle your speeds to those available when you first bought into the plan (Edge, vs LTE).

It is very clearly a reduction of service for "Unlimited" users to encourage them to drop the plan for the tiered pricing, which has no speed restrictions. Verizon just got slapped around by the FCC for doing this. AT&T is due.

Back in dial-up days, companies tried the same kind of crap and got punished for it. Eventually ISPs shifted to truly unlimited plans. Later, rinse, and repeat.

If every employee suddenly were running up internet costs, you can bet your ass companies will start blocking internet access unless you go through the hassle of proving you need it.

Say goodbye to free wifi at coffee shops.

Your phone would be affected as well, so there goes more skyrocketing costs.

No-one will download security updates if they now have to pay for the transmission.

The result of this would be the internet in the affected country reverting to user behaviors, features, and services from 10 years ago as it would introduce a sever stifling effect on data usage. Your described pattern would be what most people would do, and the internet as we've grown to know it would die.

This was a big plot point in a scifi novel I read years ago. A group of people willingly underwent amputation to reduce the mass of legs, allowing them to add more people to their launch crew.

If I remember correctly, there is a staged automobile accident, causing the main character to lose his legs (not knowing it was intentional) resolving the problem of being separated from the love interest who would be on the shuttle.

This is really going to bother me until I can remember what novel it was.
