Introduction: 20. Explain in two sentences why we expect survey respondents to be honest about vote preferences but possibly dishonest about reporting unhealty behaviors. Solution to question 19 From yesterday : 19. A survey is taken of students in a metropolitan area. At the first stage a school is sampled at random. The schools are divided into two strata: 20 private schools and 50 public schools are sampled. At the second stage, 5 classes are sampled within each sampled school. At the third stage, 10 students are sampled within each class. What is the probability that any given student is sampled? Express this in terms of the number of students in the class, number of classes in the school, and number of schools in the area. Define appropriate notation as needed. Solution: Probability a student is sampled is A*B*C, where A = 20/(# private schools) if the student is at a private school, or 50/(# public schools) if the student is at a public school, B = 5/(# classes in the student

3 0.11799348 1316 andrew gelman stats-2012-05-12-black and Black, white and White

Introduction: I’ve always thought it looked strange to see people referred to in print as Black or White rather than black or white. For example consider this sentence: “A black guy was walking down the street and he saw a bunch of white guys standing around.” That looks fine, whereas “A Black guy was walking down the street and he saw a bunch of White guys standing around”—that looks weird to me, as if the encounter was taking place in an Ethnic Studies seminar. But maybe I’m wrong on this. Jay Livingston argues that black and white are colors whereas Black and White are races (or, as I would prefer to say, ethnic categories) and illustrates with this picture of a white person and a White person: In conversation, I sometimes talk about pink people, brown people, and tan people, but that won’t work in a research paper. P.S. I suspect Carp will argue that I’m being naive: meanings of words change across contexts and over time. To which I reply: Sure, but I still have to choose h

4 0.1151122 93 andrew gelman stats-2010-06-17-My proposal for making college admissions fairer

Introduction: After reading the Rewarding Strivers book , I had some thoughts about how to make the college admissions system more fair to students from varying socioeconomic backgrounds. Instead of boosting up the disadvantaged students, why not pull down the advantaged students? Here’s the idea. Disadvantaged students are defined typically not by a bad thing that they have, but rather by good things that they don’t have: financial resources, a high-quality education, and so forth. In contrast, advantaged students get all sorts of freebies. So here are my suggestions: 1. All high school grades on a 4-point scale (A=4, B=3, etc). No more of this 5-points-for-an-A-in-an-AP course, which gives the ridiculous outcomes of kids graduating with a 4.3 average, not so fair to kids in schools that don’t offer a lot of AP classes. 2. Subtract points for taking the SAT multiple times. A simple rule would be: You can use your highest SAT score, but you lose 50 points for every other time

Introduction: Phil Harris and Bruce Smith write: We have only recently chanced upon your blog while we were looking for responses to the “decline effect” in medical and scientific studies. We were especially taken by your comment that there is something wrong with the scientific method “if this method is defined as running experiments and doing data analysis in a patternless way and then reporting, as true, results that pass a statistical significance threshold.” To us, that seems to be standard operating procedure in much of social science, including our own field of education. Indeed quasi-experimental designs are the stock in trade of those who attempt to use “science” — we dare not say haruspicy, but you can if you like — to influence the course of public policy. Now, a new entrant into the cherry pickers sweepstakes seems to have emerged. It is on Charter School Performance in Indiana Schools .

2 0.86380059 1803 andrew gelman stats-2013-04-14-Why girls do better in school

Introduction: Wayne Folta writes, “In light of your recent blog post on women in higher education, here’s one I just read about on a techie website regarding elementary education”: Why do girls get better grades in elementary school than boys—even when they perform worse on standardized tests? New research . . . suggests that it’s because of their classroom behavior, which may lead teachers to assign girls higher grades than their male counterparts. . . . The study, co-authored by [Christopher] Cornwell and David Mustard at UGA and Jessica Van Parys at Columbia, analyzed data on more than 5,800 students from kindergarten through fifth grade. It examined students’ performance on standardized tests in three categories—reading, math and science-linking test scores to teachers’ assessments of their students’ progress, both academically and more broadly. The data show, for the first time, that gender disparities in teacher grades start early and uniformly favor girls. In every subject area, bo

Introduction: Mark Palko points to a news article by Michael Winerip on teacher assessment: No one at the Lab Middle School for Collaborative Studies works harder than Stacey Isaacson, a seventh-grade English and social studies teacher. She is out the door of her Queens home by 6:15 a.m., takes the E train into Manhattan and is standing out front when the school doors are unlocked, at 7. Nights, she leaves her classroom at 5:30. . . . Her principal, Megan Adams, has given her terrific reviews during the two and a half years Ms. Isaacson has been a teacher. . . . The Lab School has selective admissions, and Ms. Isaacson’s students have excelled. Her first year teaching, 65 of 66 scored proficient on the state language arts test, meaning they got 3′s or 4′s; only one scored below grade level with a 2.

Introduction: Sharon Otterman reports : When report card grades were released in the fall for the city’s 455 high schools, the highest score went to a small school in a down-and-out section of the Bronx . . . A stunning 94 percent of its seniors graduated, more than 30 points above the citywide average. . . . “When I interviewed for the school,” said Sam Buchbinder, a history teacher, “it was made very clear: this is a school that doesn’t believe in anyone failing.” That statement was not just an exhortation to excellence. It was school policy. By order of the principal, codified in the school’s teacher handbook, all teachers should grade their classes in the same way: 30 percent of students should earn a grade in the A range, 40 percent B’s, 25 percent C’s, and no more than 5 percent D’s. As long as they show up, they should not fail. Hey, that sounds like Harvard and Columbia^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H various selective northeastern colleges I’ve known.

1 0.95938265 179 andrew gelman stats-2010-08-03-An Olympic size swimming pool full of lithium water

Introduction: As part of his continuing plan to sap etc etc., Aleks pointed me to an article by Max Miller reporting on a recommendation from Jacob Appel: Adding trace amounts of lithium to the drinking water could limit suicides. . . . Communities with higher than average amounts of lithium in their drinking water had significantly lower suicide rates than communities with lower levels. Regions of Texas with lower lithium concentrations had an average suicide rate of 14.2 per 100,000 people, whereas those areas with naturally higher lithium levels had a dramatically lower suicide rate of 8.7 per 100,000. The highest levels in Texas (150 micrograms of lithium per liter of water) are only a thousandth of the minimum pharmaceutical dose, and have no known deleterious effects. I don’t know anything about this and am offering no judgment on it; I’m just passing it on. The research studies are here and here . I am skeptical, though, about this part of the argument: We are not talking a

So do you recommended any reference to complement your book on covariance structures typical from these models, such as AR(1), Antedependence, Factor Analytic, etc? I am very much interest in BUGS code for these basic models as well as how to extend them to more complex situations. My reply: There is a book by Banerjee, Carlin, and Gelfand on Bayesian space-time models. Beyond that, I think there is good work in psychometrics on covaraince structures but I don’t know the literature.

Introduction: Chris Wiggins writes of an interesting-looking summer program that undergraduate or graduate students can apply to: The hackNY Fellows program is an initiative to mentor the next generation of technology innovators in New York, focusing on tech startups. Last summer’s class of fellows was paired with NYC startups which demonstrated they could provide a mentoring environment (a clear project, a person who could work with the Fellow, and sufficient stability to commit to 10 weeks of compensation for the Fellow). hackNY, with the support of the Kauffman foundation and the Internet Society of New York, provided shared housing in NYU dorms in Union Square, and organized a series of pedagogical lectures. hackNY was founded by Hilary Mason, chief scientist at bit.ly, Evan Korth, professor of CS at NYU, and Chris Wiggins, professor of applied mathematics at Columbia. Each of us has spent thousands of student-hours teaching and mentoring, and is committed to help build a strong communi

5 0.93643373 593 andrew gelman stats-2011-02-27-Heat map

Introduction: Jarad Niemi sends along this plot: and writes: 2010-2011 Miami Heat offensive (red), defensive (blue), and combined (black) player contribution means (dots) and 95% credible intervals (lines) where zero indicates an average NBA player. Larger positive numbers for offensive and combined are better while larger negative numbers for defense are better. In retrospect, I [Niemi] should have plotted -1*defensive_contribution so that larger was always better. The main point with this figure is that this awesome combination of James-Wade-Bosh that was discussed immediately after the LeBron trade to the Heat has a one-of-these-things-is-not-like-the-other aspect. At least according to my analysis, Bosh is hurting his team compared to the average player (although not statistically significant) due to his terrible defensive contribution (which is statistically significant). All fine so far. But the punchline comes at the end, when he writes: Anyway, a reviewer said he hated the
