Barry Schouten is a Senior Methodologist in the Division of Methodology and Quality at Statistics Netherlands. Dr. Schoutens research interests include nonresponse bias, measurement error, mixed-mode surveys, and adaptive or responsive survey design. He is a principal developer of the R-Indicator, a new measure of survey quality that measures how well a set of respondents resembles the sample based on covariates measured on the full sample. He is also developing new, adaptive survey designs in the mixed-mode setting that maximize the R-Indicator while minimizing the risk of measurement error.
