Peter Lugtig - Survey methodology: Which devices do respondents use over the course of a panel study?
http://www.peterlugtig.com/2014/12/what-devices-do-respondents-use-over.html
Peter Lugtig - Survey methodology. Weblog and personal homepage. Tuesday, December 2, 2014. Which devices do respondents use over the course of a panel study? And I have been writing a few articles over the last two years about how survey respondents are taking up tablet computers and smartphones. We were interested in studying whether people in a probability-based web panel (. The table below shows that PC users largely stick to their PC in all waves. For example, we see that 77.4% of PC-respond...More ...
Peter Lugtig - Survey methodology: Are item-missings related to later attrition?
http://www.peterlugtig.com/2014/04/are-item-missings-related-to-later.html
Peter Lugtig - Survey methodology. Weblog and personal homepage. Tuesday, April 29, 2014. Are item-missings related to later attrition? A follow up on last month's post. Respondents do seem to be less compliant in the waves before they drop out from a panel survey. This may however not neccesarily lead to worse data. So, what else do we see before attrition takes place? Let have a look at missing data:. First, we look at missing data in a sensitive question on income amounts. Earlier studies ( here.

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.

Andy's Survey Methodology Blog: Are we ready for a single-frame cell phone survey design?
http://andypeytchev.blogspot.com/2012/12/are-we-ready-for-single-frame-cell.html
Andy's Survey Methodology Blog. Saturday, December 15, 2012. Are we ready for a single-frame cell phone survey design? It feels as if in this rapidly changing social and technological environment, surveys methods are merely trying to catch up with changes. It took a while for RDD telephone surveys to incorporate cell phone numbers. It took more time for researchers to use sample optimization formulas for allocation of sample across frames. Why could this be the case? View my complete profile. James Wagne...
Andy's Survey Methodology Blog: Are We Done Yet?
http://andypeytchev.blogspot.com/2010/02/are-we-done-yet.html
Andy's Survey Methodology Blog. Saturday, February 13, 2010. Are We Done Yet? Commonly, surveys have a target number of interviews, together with a target response rate. The number of interviews can be determined by a desired precision of survey estimates based on variance assumptions. Most surveys have multiple objectives, producing numerous estimates and even types of analysis. But what if a survey has a focal objective, such that survey data collection can be geared towards that objective? I am a Rese...

I was asked to write a paper on the consequences of unit nonresponse in surveys ( http:/ ann.sagepub.com/content/645/1/88. I did a simple analysis for this paper that I found particularly intriguing. While a meta-analysis by Groves and Peytcheva found lack of association between nonresponse rates and nonresponse bias across. View my complete profile. The Cost of a Call Attempt.

Andy's Survey Methodology Blog: Is this a cell phone, a landline, or both? The demise of landlines as a technology?
http://andypeytchev.blogspot.com/2013/07/is-this-cell-phone-landline-or-both.html
Andy's Survey Methodology Blog. Tuesday, July 23, 2013. Is this a cell phone, a landline, or both? The demise of landlines as a technology? Currently, Random Digit Dial (RDD) telephone surveys can field samples from the landline and from the cell phone frames (sets of exchanges assigned to either service). The interviewers could confirm with the respondent whether they have reached a landline or a cell phone, and assign them to the correct stratum for weighting and estimation.

Andy's Survey Methodology Blog. Wednesday, January 23, 2013. The Three Sampling Distributions of Polls . and Surveys? I just listened to a pollster describe polls relying increasingly more on art than science. Decisions on how to identify likely voters, how to weigh the data, etc. And it made me think: could we not quantify the Art part so that it becomes Science? View my complete profile.

Andy's Survey Methodology Blog: Mail vs. Telephone; ABS vs. RDD

Andy's Survey Methodology Blog. Friday, February 19, 2010. Mail vs. Telephone; ABS vs. RDD. The telephone survey methodology conference II and the resulting book, Advances in Telephone Survey Methodology, have shown problems and solutions to the use of random-digit-dialing (RDD) and telephone to conduct surveys. Others have used growing challenges with RDD, both cost and coverage related, as arguments for the use of entirely new approaches to current studies. A guess would be "not much." Further rese...
Andy's Survey Methodology Blog: Missed Opportunities to Make Use of Large Scale Survey Experiments

Andy's Survey Methodology Blog. Tuesday, March 26, 2013. Missed Opportunities to Make Use of Large Scale Survey Experiments. Unfortunately, the data from these large scale methodological experiments are usually not publicly released. This is not through inadvertent oversight. At a minimum, there is cost associated with preparing and releasing data files - resources that are needed on the particular survey being redesigned. It does make me wonder if external research funding could be dedicated to making d...
