Introduction: Interesting discussion here by Mark Palko on the difficulty of comparing charter schools to regular schools, even if the slots in the charter schools have been assigned by lottery. Beyond the direct importance of the topic, I found the discussion interesting because I always face a challenge in my own teaching to assign the right amount of homework, given that if I assign too much, students will simply rebel and not do it. To get back to the school-choice issue . . . Mark discussed selection effects: if a charter school is popular, it can require parents to sign a contract agreeing they will supervise their students to do lots of homework. Mark points out that there is a selection issue here, that the sort of parents who would sign that form are different from parents in general. But it seems to me there’s one more twist: These charter schools are popular, right? So that would imply that there is some reservoir of parents who would like to sign the form but don’t have the opp

2 0.67427111 513 andrew gelman stats-2011-01-12-“Tied for Warmest Year On Record”
Introduction: The National Climatic Data Center has tentatively announced that 2010 is, get this, “tied” for warmest on record. Presumably they mean it’s tied to the precision that they quote (1.12 F above the 20th-century average). The uncertainty in the measurements, as well as some fuzziness about exactly what is being measured (how much of the atmosphere, and the oceans) makes these global-average things really suspect. For instance, if there’s more oceanic turnover one year, that can warm the deep ocean but cool the shallow ocean and atmosphere, so even though the heat content of the atmosphere-ocean system goes up, some of these “global-average” estimates can go down. The reverse can happen too. And of course there are various sources of natural variability that are not, these days, what most people are most interested in. So everybody who knows about the climate professes to hate the emphasis on climate records. And yet, they’re irresistible. I’m sure we’ll see the usual clamor of som
3 0.65259618 491 andrew gelman stats-2010-12-29-Don’t try this at home
Introduction: Malecki’s right, this is very cool indeed. P.S. Is it really true that “4.5 million Parisians” ride the Metro every day? Even setting aside that not all the riders are Parisians, I’m guessing that 4.5 million is the number of rides, not the number of people who ride.
4 0.63380122 68 andrew gelman stats-2010-06-03-…pretty soon you’re talking real money.
Introduction: A New York Times article reports the opening of a half-mile section of bike path, recently built along the west side of Manhattan at a cost of $16M, or roughly $30 million per mile. That’s about $5700 per linear foot. Kinda sounds like a lot, doesn’t it? Well, $30 million per mile for about one car-lane mile is a lot, but it’s not out of line compared to other urban highway construction costs. The Doyle Drive project in San Francisco — a freeway to replace the current old and deteriorating freeway approach to the Golden Gate Bridge — is currently under way at $1 billion for 1.6 miles…but hey, it will have six lanes each way, so that isn’t so bad, at $50 million per lane-mile. And there are other components to the project, too, not just building the highway (there will also be bike paths, landscaping, on- and off-ramps, and so on). All in all it seems roughly in line with the New York bike lane project. Speaking of the Doyle Drive project, one expense was the cost of movin
5 0.63217497 1845 andrew gelman stats-2013-05-07-Is Felix Salmon wrong on free TV?
Introduction: Mark Palko writes : Salmon is dismissive of the claim that there are fifty million over-the-air television viewers: The 50 million number, by the way, should not be considered particularly reliable: it’s Aereo’s guess as to the number of people who ever watch free-to-air TV, even if they mainly watch cable or satellite. (Maybe they have a hut somewhere with an old rabbit-ear TV in it.) And he strongly suggests the number is not only smaller but shrinking. By comparison, here’s a story from the broadcasting news site TV News Check from June of last year (if anyone has more recent numbers please let me know): According to new research by GfK Media, the number of Americans now relying solely on over-the-air (OTA) television reception increased to almost 54 million, up from 46 million just a year ago. The recently completed survey also found that the demographics of broadcast-only households skew towards younger adults, minorities and lower-income families. As Palko says,

1 0.98399198 1088 andrew gelman stats-2011-12-28-Argument in favor of Ddulites
Introduction: Mark Palko defines a Ddulite as follows: A preference for higher tech solutions even in cases where lower tech alternatives have greater and more appropriate functionality; a person of ddulite tendencies. Though Ddulites are the opposite of Luddites with respect to attitudes toward technology, they occupy more or less the same point with respect to functionality. As a sometime Luddite myself (no cell phone, tv, microwave oven, etc.), I should in fairness point out the logic in favor of being a Ddulite. Old technology is typically pretty stable; new technology is improving. It can make sense to switch early (before the new technology actually performs better than the old) to get the benefits of being familiar with the new technology once it does take off.
