In this panel discussion at @GESIS, in context of the KODAQS project , a panel discussion one important aspect of data quality: representation. To this end,I discuss with Henning Silber , Stephanie Eckman and Barbara Felderer the nuts and bolts of representation and sampling, including the notion of good representation, ways to achieve or to measure it, challenges on the way towards good representation, probabilistic and non-probabilistic samples, and innovative ways to supplement traditional survey data.
In this talk in Feb 2024 in the context of the EMOS webinar series , I talked about smart surveys, in particular the work done over the period 2017-2022 with Statistics Netherlands, and an an going research project ‘Smart Survey Implementation’ funded by Eurostat over the period 2023-2025.
Live-recording of keynote: “What Internet panel surveys can learn from the design of smartphone-app studies.”
Several studies have explored using smartphone-apps as a way to collect social and behavioral data. Some notable successful studies have in recent years been conducted in the context of travel behavior, time use, household consumption, or ‘in-the-moment’ attitudinal measures about a variety of subjects.
One characteristic of smartphone studies is that they follow participants over a period of time to measure (short-term) changes.
Pre-recorded conference presentation: “quality of measurements from smartphone travel-app study”
Smartphone apps are starting to be commonly used to measure travel behaviour. The advantage of smartphone apps is that they can use location sensors in mobile phones to keep track of where people go at what time at relatively high precision. In this presentation, we report on a large fieldwork test conducted by Statistics Netherlands and Utrecht University in November 2018.
