Andy's Survey Methodology Blog: Optimizing dual-frame RDD sample designs
http://andypeytchev.blogspot.com/2010/01/optimizing-dual-frame-rdd-sample.html
Andy's Survey Methodology Blog. Sunday, January 31, 2010. Optimizing dual-frame RDD sample designs. Mike Brick presented an interesting short course through ASA/SRMS last year, presenting much-needed work on optimum allocation of sample. S from landline and cell phone frames. In his examples, made-up numbers for cost per interview were used. Unfortunately, it is the cost estimates themselves. 1 A dual frame study should not use a landline sample from. I am a Research Assistant Professor at the Institute ...

Survey Methods Musings: Is the "long survey" dead?
http://jameswagnersurv.blogspot.com/2015/05/is-long-survey-dead.html
Blogging about survey methods, responsive design, and all things survey related. Friday, May 29, 2015. Is the "long survey" dead? A colleague sent me a link to a blog. Arguing that the "long survey" is dead. The blog takes the point of view that anything over 20 minutes is long. There's also a link to another blog. In my world 20 minutes is still a short survey. But the point is still taken. There has been some research. Matrix sampling is another useful approach that is little used. It seems like yo...

Survey Methods Musings: May 2015
http://jameswagnersurv.blogspot.com/2015_05_01_archive.html
Blogging about survey methods, responsive design, and all things survey related. Friday, May 29, 2015. From average response rate to personalized protocol. Researchers have since looked at subgroup response rates. Also interesting, but assuming that these rates are a fixed characteristic leaves us helpless. Now, it seems that we have begun working with an assumprton that there is heterogenous response to treatments and that we should, therefore, tailor the protocol and manipulate response propensities.

Survey Methods Musings: February 2015
http://jameswagnersurv.blogspot.com/2015_02_01_archive.html
Blogging about survey methods, responsive design, and all things survey related. Friday, February 13, 2015. Adaptive Designs and Incentives. I've been working on a paper about an incentive experiment that we did. It raised some interesting issues. And made me recall one of my favorite papers. Trussell and Lavrakas. There are all sorts of ethical and procedural issues with offering differential incentives that make it difficult to carry out in practice, but I still think this is a neat example. I had the ...

Survey Methods Musings: September 2014
http://jameswagnersurv.blogspot.com/2014_09_01_archive.html
Blogging about survey methods, responsive design, and all things survey related. Friday, September 26, 2014. Web Panels vs Mall Intercepts. I saw this interesting article. That just came out. It called to my mind a talk that was hosted here a few (8? Wednesday, September 17, 2014. Idenitfying all the components of a design, again. In my last post I talked about identifying all the components of a design. At least identifying them is an important step if we want to consider randomizing them. Of co...I fir...

Survey Methods Musings: Selection Effects
http://jameswagnersurv.blogspot.com/2015/05/selection-effects.html
Blogging about survey methods, responsive design, and all things survey related. Friday, May 8, 2015. This seems to come up in a number of different ways frequently. We talk a lot about nonresponse and how it may be a selective process such that it produces biases. We might try to model this process in order to correct these biases. If not, what else do we need to know? Subscribe to: Post Comments (Atom). View my complete profile. From average response rate to personalized protoco.

http://jameswagnersurv.blogspot.com/2014_05_01_archive.html
Blogging about survey methods, responsive design, and all things survey related. Friday, May 30, 2014. Last week, I mentioned an experiment that we ran with changing the order of tracking steps. I noted that the overall result was that the original, expert-chosen order worked better than the new, proposed order. Friday, May 23, 2014. Tracking: Does Sequence Matter? That varied the order of steps. Friday, May 16, 2014. More on Measurement Error. Makes this point. If I have the "right" structure for my...

Survey Methods Musings: July 2014
http://jameswagnersurv.blogspot.com/2014_07_01_archive.html
Blogging about survey methods, responsive design, and all things survey related. Friday, July 25, 2014. Responsive Design and Uncertainty. To my mind, a key reason for responsive designs is uncertainty. This uncertainty can probably occur in at least two ways. First, at a survey. Level, I can be uncertain about what response rate a certain protocol can elicit. If I don't obtain the expected response rate after applying the initial protocol, then I can change the protocol and try a different one. I had to...

Survey Methods Musings: November 2014
http://jameswagnersurv.blogspot.com/2014_11_01_archive.html
Blogging about survey methods, responsive design, and all things survey related. Friday, November 21, 2014. I came across this interesting po. About building a Bayesian model with careful specification of priors. The problem is that they have "tiny" data. So the priors play an important role in the analysis. I liked this idea of "tiny" data. The rush to solve problems for "big data" has obscured the fact that are interesting problems for situations where you don't have much data. I would argue that turni...
