It seems as though reseach online has recently reinvented themselves. They were always a great source for information, but they seem to be exploding with news and original content lately.
A recent article titled "Survey Geek vs. The Cord-Cutters" offers an audio interview with self-confessed 'survey geek' and blogger, Reg Baker. There are also great links to relevant articles on the cell-only population and the affects on research. You can listen to it here:
This interview is great in my opinion, particularly in that he begins by describing the "cell-only" problem in terms of the sampling frame. He also eloquently yet concisely descsribes the issue of bias due to undercoverage, and how the target group of the research and the topic may affect results. Not to mention cost and data implications of doing a survey on mobile phone. Reg also identifies the "wireless mostly" problem. I won't replicate every point here in text, but here's a researcher who knows his stuff.
Brilliantly, he surmises (and hopes) that researchers will adapt to the problem by matching the method to the problem - execute "fit-for-purpose methodology decision", to paraphrase slightly.
But one thing stuck out to me... there's no mention of three significant and growing ways to conduct a mobile device survey, cellphone survey, mobile marketing survey (mobile research by whatever name you choose): WAP, SMS and Survey Applications.
Check out the latest numbers from CASRO. You might find it's worth getting ahead of the curve by adding other mobile techniques to your methodological tool box.
