Mixing Online Panel Data Collection with Innovative Methods

Mixed mode studies in survey research have been around since a long time. Whenever a new mode of data collection emerges, it has been combined with existing traditional modes of data collection, and compared in terms of resulting response rates, response bias, data quality and measurement error (Couper 2011, for general overviews of traditional mixed mode studies see de Leeuw 2005 and De Leeuw et al. 2008).
