Abstract:

This presentation describes the results of two studies conducted by ICM Research and MSTS. The first, The Research Buyers Survey, describes work undertaken amongst a range of research buyers to understand their views of different data collection methodologies. The second study involves two experimental tests to examine what mode effects exist when the same respondents are asked the same questions via different methodologies. This presentation also draws on other original research studies conducted by ICM and MSTS which look at issues of panel and response rate bias.
