  3. Agenda • Why We Have to Rethink Our (Web Survey) Data Collection Approaches • Respondent-Driven Use of Smartphones • Researcher-Driven Use of Smartphones • Survey Methodology in the Age of Big Data • Summary

  4. Why We Have to Rethink our (Web Survey) Data Collection Approaches Smartphone surveys, behavior tracking, and Big Data – Opportunities and challenges of new modes of survey data collection Florian Keusch

  5. Web Has Become an Established Survey Mode • Dropping response rates (esp. in CATI) and high costs (of CAPI) have led to vast adoption of Web surveys • In commercial sector, Web #1 data collection method in many countries • Mostly driven by rise of nonprobability online panels

  6. Rise of Web Surveys 33% of worldwide marketing research sales come from web surveys (ESOMAR 2015) Source: https://www.adm-ev.de/zahlen/

  7. Web Has Become an Established Survey Mode • Dropping response rates (esp. in CATI) and high costs (of CAPI) have sped up SIEGESEZUG of Web surveys • In commercial marketing research, Web clear #1 data collection method in many countries • Mostly driven by rise of nonprobability online panels • Proliferation of DIY Web survey platforms and widespread use of in-house Web survey tools • SurveyMonkey reports 90M survey completes per month (Bort 2015) • Qualtrics distributes 1B surveys annually (Callegaro & Yang in print) • More and more large scale survey projects experimenting with/adding Web survey component/supplement • UKHLS, HRS, ALLBUS, ESS, SCA, ACS, ANES • Establishment of (academic) probability online panels

  8. (Academic) Probability Online Panels • German Internet Panel (GIP): http://reforms.uni-mannheim.de/internet_panel/home/ • Gesis Panel: http://www.gesis.org/en/services/data-collection/gesis-panel/ • Longitudinal Study by Internet for the Social Sciences (ELIPSS): https://www.elipss.fr/ • Longitudinal Internet Studies for the Social Sciences (LISS): https://www.lissdata.nl/lissdata/About_the_Panel • KnowledgePanel: http://join.knpanel.com/about.html • AmeriSpeak: http://www.norc.org/Research/Capabilities/Pages/amerispeak.aspx • American Trends Panel: http://www.pewresearch.org/methodology/u-s-survey-research/american-trends-panel/ • Understanding America Study: https://uasdata.usc.edu/

  9. Interested in Web Survey Methodology?

  10. Another Technological Revolution? “If you're doing a Web survey,you're doing a mobile survey.” Michael Link, Nielsen(@AAPOR 2013)

  11. Device Ownership Among U.S. Adults

  13. Two Separate Phenomena • Completion of Web surveys on mobile Web devices (i.e., respondent-driven use of smartphone) • PC-optimized Web surveys completed by some on mobile devices • “Unintentional mobile Rs” (Peterson 2012) • Hope to increase coverage or reduce nonresponse, without affecting data quality • Use of mobile Web for new methods of data collection (i.e., researcher-driven use of smartphones) • Examples: ecological momentary assessment (EMA), diary studies, travel studies, health monitoring, passive mobile data collection • Based on volunteers, who have to download and install an app

  14. Respondent-Driven Use of Smartphones Smartphone surveys, behavior tracking, and Big Data – Opportunities and challenges of new modes of survey data collection Florian Keusch

  15. Empirical Evidence for Unintentional Mobile Rs • Non-probability online panels: • Peterson (2012): between 1% and 30% of all Rs in U.S., depending on target population • Kinesis (2013): 51% of marketing research surveys started on mobile device in U.S., 10% in Europe • Revilla et al. (2015): 7.1% of all Netquest panel members used smartphones and 1.8% tablets in 2013 and 2014; strong increase over time • Probability online panels: • de Bruijne & Wijnant (2014): share of unintended mobile increased in LISS panel from 3.1% in March 2012 (0.4% smartphones, 2.6% tablets) to 10.9% in September 2013 (1.6% smartphones, 9.3% tablets) • Struminskaya et al. (2015): 8% of Rs used mobile device at least once in GESIS Pilot Panel’s 8 survey waves (2.1% mobile users in at least 7 waves) • Pew Research Center’s (2015a): 27% of Rs in American Trends Panel completed most recent survey on a smartphone, 8% used tablet

  17. Nonresponse in Mobile Web Surveys • Evidence that RR lower and break-off rate higher for mobile Web than PC Web1,2, even when optimizing for mobile devices3,4,5,6,7 • Longer response times1,2,3,6,7,8 • Higher burden for participation • Much of difference due to within-page times (i.e., answering, scrolling), not between-page times (i.e., connection speed)9 • Smartphone Rs younger1,6,7,8, female7,8, heavier mobile Web users1, and primarily rely on smartphones to access Internet7 Source: 1Mavletova (2013); 2Mavletova & Couper (2013); 3Antoun (2015); 4Buskirk & Andrus (2014); 5Stapleton (2013);6Toepoel & Lugtig (2014); 7Wells, et al.

  21. Measurement Error in Mobile Web Surveys • General cognitive processing seems to be same as in other modes1 • Survey completion on mobile device (especially smartphone) different than survey completion on desktop/laptop • Effects on item omission2,3,4 and primacy effects1,2,5 • Tablet seems to be more similar to desktop/laptop than smartphone • As long as care taken in design, very few (reliable) differences in responses to mobile Web and regular Web after controlling for self-selection and nonresponse4,6,7 Source: 1Peytchev & Hill (2010); 2Lugtig & Toepoel (2015); 3Mavletova & Couper (2014); 4de Bruijne & Wijnant (2013);5Stapleton (2013); 6Toepoel & Lugtig (2014); 7Peterson (2012)

  23. Keusch & Yan (2016): Survey Answers and Satisficing • Mean ratings of four individual items and means of three indexes do not sign. differ across comparisons (p>0.05) • Mode differences in straightlining* • No effect on acquiescence and mid-point responding N=1,186 U.S. iPhone owners on Mturk, who finished the study *Differences remain significant after controlling for socio-demographics and Web survey experience

  24. What We Know So Far… • For an increasing number of people, smartphones are the only way to access the Internet • If we don‘t alllow/make it difficult for them to participate in Web surveys, we might introduce nonreponse bias • Smartphones are used differently than PCs • If a Web survey design does not consider smartphone use, we might introduce measurement error • Track what device your respondents are using! • Design your web survey to be smartphone-friendly!

  25. Responsive Design

  26. What We Know So Far… • For an increasing number of people, smartphones are the only way to access the Internet • If we don‘t alllow/make it difficult for them to participate in Web surveys, we might introduce nonreponse bias • Smartphones are used differently than PCs • If a Web survey design does not consider smartphone use, we might introduce measurement error • Track what device your respondents are using! • Design your web survey to be smartphone-friendly! • Do methodological research! • e.g., questionnaire design, modularizing Web surveys, location- and behavior-based survey invitations

  27. Researcher-Driven Use of Smartphones Smartphone surveys, behavior tracking, and Big Data – Opportunities and challenges of new modes of survey data collection Florian Keusch

  28. Using Apps for Passive Mobile Data Collection Compared to Surveys, Passive Data Collection Has Potential to… • …provide richer data • Because it is collected at higher frequencies • …decrease respondent burden • Because fewer survey questions needed • …reduce measurement error • Because of less memory errors and social desirability http://www.qualitytimeapp.com/

  29. Using Apps for Passive Mobile Data Collection • Limited published research so far • Sonck & Fernee (2013): iPhone app modeled after Harmonized European Time Use Survey (HETUS) • Link et al. (2014): TV-viewing diary • Pew Research Center (2015b): Ecological momentary assessment • Revilla et al. (2016): Smartphone browsing behavior tracking • Sugie (2016): Job-seeking behavior of parolees • Several large scale research projects on the way • SOEP started to use mobile app to keep in touch with their refugee cohort • CBS and Utrecht University just formed a large-scale Innovation Network (WIN) for data collection innovation with smartphones • IAB will use mobile device measures for labor market research (MoDeM) • Modernizing Migration Measures – Combining survey and tracking data collection among refugees (MZES)

  30. MoDeM • Collaboration of University of Mannheim (F. Keusch & F. Kreuter) with IAB (F. Kreuter, M. Trappmann, S. Bähr, & G.-C. Haas) • Funded by Institute for Employment Research (IAB) • Research Question: Can we use mobile passive Data collection via smartphones for labor market research? • Combining behavior and location tracking with short mobile web surveys • Both substantial and methodological questions

  31. MoDeM: Research Design • Recruitement of participants from the "Labour Market and Social Security“ panel study (PASS) in spring 2017 • Invitation to download app to Android smartphone • App runs in background • Sends information about user activity on smartphone and other information (e.g., geolocation, signal strength, network provider) • App records activities on smartphone but not content generated • Incentives • € 10 for downloading app to smartphone • € 10 for leaving app installed on smartphone until end of field period • Push-notifications with invitations to very short surveys • Linking of app data, survey data, PASS data, and administrative data from Federal Employment Agency

  32. MoDeM: Substantial Research Questions • Social participation of unemployed – Marienthal 2.0 • Does data from sensors built into smartphones allow inference on activities and daily routines of unemployed people? • Measuring social networks • How do measures of social embeddedness/social networks generated from app data compare to standard measures used in PASS? • Formal and informal ways of job-seeking • Can we learn more about the job-seeking process from smartphone data? • Can we use geolocation data to trigger surveys on job-seeking?

  33. MoDeM: Methodological Research Questions • Optimizing push notifications for surveys • When and how often can and should smartphone users be invited to participate in short surveys? • Coverage error and nonresponse error of mobile passive tracking • Do PASS members who own an Android smartphone differ from PASS members who do not own an Android smartphone? • Do respondents and nonrespondents differ in our tracking study?

  34. Challenges so far... • Legal and ethical concerns • Consent, data linkage, and privacy • Rapid advancement of technology • Constant updates of hard- and software • Limitation to Android smartphones • Coverage error? • GIP: Android users are older than users of other OS • New skills required that survey methodologists usually don‘t have • Technical know-how to set up app • Working with Big Data

  35. Survey Methodology in the Age of Big Data Smartphone surveys, behavior tracking, and Big Data – Opportunities and challenges of new modes of survey data collection Florian Keusch

  36. Big Data • Aka “organic” or “found” data • “Organic” (Groves 2011) – not from designed survey • “Found” – not collected by researchers Source: http://www.rosebt.com/blog/data-veracity

  37. Forms of Big Data ? (Source: http://www.connexica.com/connexica_wp/wp-content/uploads/2014/12/Big-data-buzz-or-big-data-fuzz-blog-image.jpg) (Source: http://cdn2.business2community.com/wp-content/uploads/2016/06/internet-of-things.jpg) (Source: http://researchaccess.com/wp-content/uploads/2013/09/iStock_paper_questionnaire.jpg) http://pocketnow.com/2012/06/21/android-nfc-app-reveals-contactless-credit-card-details-should-you-be-worried#!prettyPhoto (Source: IAB) Source: Callegaro & Yang (in press)

  38. So Will Surveys Go Away? Maybe… Probably not… Bigger data not always better data Most Big/Found/Organic data not output of instruments designed to produce valid and reliable data for scientific analysis Data generation in many cases a “black box” Surveys will be needed in the future… …in combination with other forms of data …as benchmark to gauge success of social media research …for attitudinal data • Censuses replaced by administrative records in some countries • In the US, sales from “automated digital/electronic” (35%) already far ahead of online surveys (20%) (ESOMAR 2015) • Web scraping allows predictions of, for example, inflation (e.g., Billion Price Project, Price Stats) • …

  41. Summary Smartphone surveys, behavior tracking, and Big Data – Opportunities and challenges of new modes of survey data collection Florian Keusch

  42. Summary • For an increasing number of people, smartphones are the only way to access the Internet • Design your web survey to be smartphone-friendly! • Researchers can use smartphones for more than just Web surveys • Location- and behavior-based survey invitations • Combining mobile web surveys with passive data collection • We need to better understand what drives people to participate/not paticipate in passive mobile data collection • More research needed to understand influence of smartphones on data quality (coverage, nonresponse, measurement) • Survey methodologists need to embrace their role in a changing environment • Experts on data generation and data quality
