Research Interests

For more than twenty years I have been investigating how different visual languages (words, graphics, symbols and numbers) independently and collectively influence answers to survey questions in web and paper surveys. I am also interested in how the use of visual language in such surveys may influence respondents to provide different answers than they do in aural language surveys by telephone. The results of this research are being used to guide to develop guidelines  (see 2014 book listed below) for designing and conducting mixed-mode surveys, which are becoming increasingly important as a means of improving the accuracy of survey results. However, the main emphasis of my current research is on how to effectively utilize addressed-based sampling methods to encourage survey respondents to complete web surveys, instead of telephone or mail surveys. I am active in applying the results of my research to designing national surveys conducted by the U.S. Census Bureau, USDA, National Science Foundation, Bureau of Labor Statistics, and other agencies that provide statistical estimates for making major policy  decisions.
